Seriously...

Lots of people wear wigs, and go to great lengths to keep them secret - but why? Perhaps it's because the hair on top of our heads means so much to us. It's a crucial part of our identity, the person we see when we look in the mirror, so what happens when it's not there?It's a question Brian Kernohan has asked himself. Yes, his hair's thinning a bit on top, but it's his secret - until his hairdresser points it out. Brian wouldn't dare suggest a wig - even though he's always wondered if he could try one?Brian investigates the secret world of wigs with the help of alopecia sufferer Geraldine, who runs a secret wig shop which ensures discretion for all her customers. He explores the stigma attached to wig wearing, and finds out how tastes have changed since the 17thcentury when Louis XIV put wigs at the cutting edge of fashion. He meets cancer patients who have learnt to "embrace your inner bald", as 16-year-old Sophie puts it, the wig shop owner who surprises customers by wearing her own stock, and meets the opera singer who loves to wear wigs on stage. But still, Brian is nervous when he is fitted for a wig, and is even more terrified when he has to wear it in public. What if someone realises he's wearing a secret wig - and why does he care so much? Producer: Freya McClements.

With more than 30 million presentations being given around the world every day, PowerPoint has become the single most ubiquitous tool for presenting ideas. Yet it's the software many of us love to hate - vilified for simplifying the complex and complicating the simple. 30 years on from its commercial launch, Ian Sansom asks, 'What's the real point of PowerPoint?' as he embarks on what surely must be a world first - a PowerPoint presentation for the radio.How do I move this on to the next slide? There we are. Thanks. Armed only with an auto-content wizard, some zippy graphics and a hefty set of bullet points, Ian ventures forth to assess the true impact of this revolution in communication. He speaks with the software's pioneers, meets some of its notable detractors and asks how PowerPoint has influenced corporate life and spilled out into some improbable areas of our culture. As he discovers how science-fiction is helping to inform the next generation of presentation technology, Ian asks if PowerPoint has empowered the individual - or if our boardrooms, lecture halls and even our spiritual affairs are to be forever condemned to the fate that has come to be known as 'Death By PowerPoint.' What do I do now? Press escape? No, I want to bring it back to the start. F6 I think. Where's the remote thingy..?Producer: Conor Garrett.

After the violence directed at black people in Nottingham and Notting Hill in the 1950s, and the naked racism expressed in Smethwick during the 1964 general election, a group of pioneering West Indians came up with a simple and defiant riposte: Carnival. In Queens of Chapeltown, Colin Grant goes behind the scenes of Carnival to its Leeds West Indian HQ in Chapeltown - amidst the glue guns, sequins and feathers - to capture that moment of extraordinary transformation, 50 years on: the birth of a tradition which, for one weekend in August, would wash away the bad taste of anti immigrant sentiment with a burst of colour and flash of exuberance that would forever change Britain. Grant travels to Leeds to talk with the pioneers and celebrate the endurance and growth of Carnival.Produced and presented by Colin Grant.

Suicide is the number one killer of men under-50 in England and Wales. A 'zero suicide' approach to prevention first devised in Detroit is now changing attitudes to care in the UK. Merseyside is leading the way. Radio 4 gains exclusive access to a healthcare authority being transformed from the inside-out in a bid to treat suicide as a preventable condition and to bring lives lost down to 0% by 2020.

Grayson Perry goes backwards in the archive in search of the moment the avant-garde died.It's a century since Marcel Duchamp submitted his artwork called Fountain to an exhibition staged by the Society of Independent Artists in New York. Fountain was a urinal -- not a painting of a urinal or a sculpture, just a urinal, bought from a Manhattan hardware store and signed R.Mutt. The Society of Independent Artists rejected Duchamp's provocation and the original object was lost.Nowadays Duchamp's urinal is canonised as the fountainhead of conceptual art and the high water (closet) mark of the avant garde. Replicas of the Fountain grace museums around the world - emblems of the avant-garde spirit of experimentation and confrontation. Somewhere in the intervening years though, something changed - contemporary art lost its ability to shock and critique. We're still hopelessly drawn to the idea of art that's 'cutting edge', 'ground-breaking', 'revolutionary'. But is that possible at this point -- haven't we seen it all before?Maybe the death knell was sounded when the Saatchi Gallery opened on the South Bank? Or with the advent of protest and radical chic in the 1960s? Maybe it was when the CIA funded the abstract expressionists? Or when the post-war art market began to reign supreme? Or when the Museum of Modern Art opened its doors in 1927?Or maybe it was all a matter of style the very moment Duchamp's Fountain was conceived?Featuring Brian Eno, Kenneth Goldsmith, Nnenna Okore, Cornelia Parker, and Sarah Thornton.Producer: Martin Williams.

Bill Drummond is many things. As well as an artist, a writer and former pop-star - he's the owner of an old curfew tower in Northern Ireland which he runs as an artists' residency. Last year some poets from Belfast's Seamus Heaney Centre for Poetry stayed there and Bill published their collected work in a little black book called The Curfew Tower is Many Things. Except for a poem the award-winning Belfast poet Stephen Sexton wrote. Apparently that one went missing. So Bill has left two pages blank in the book for Stephen to fill in with poetry as they drive through all of Ireland's 32 counties in 5 days in a white Ford Transit hire-van, giving out copies as they go. But what exactly is driving Bill Drummond? Producer Conor Garrett is there to find out. As they cross the Irish border and over each county boundary, Conor is becoming increasingly concerned he may not have a good enough story for his radio programme. It's a problem further complicated by the fact Bill won't talk about his chart-topping '90s pop band who once famously set fire to a very large pile of their own cash. Then, when a narrative arc does eventually develop, Conor can't be sure how authentic it is. And what's all this stuff about eels?Producer: Conor Garrett.

It's time to travel down the rabbit hole of truth as American satirist Joe Queenan explores a murky world of fake news, prejudice and alternative facts. "Recent politics have shown that the truth is no fun," he explains. "It's like a vegetable your mother makes you eat. Yes it may be nourishing, but it tastes terrible." With archive contributions from Donald Trump, Doris Lessing, Jeremy Corbyn, Peter Mandelson and Theresa May; plus new interviews with Mark Borkowski, Edith Hall and Julian Baggini, author of a Short History of Truth. This is Joe Queenan's follow up to previous editions on Blame, Shame, Irony and Anger.The producer in Bristol is Miles Warde.

The sound of music flying through the air, carried on the tails of pigeons. "I knew it was a noise maker, but it was the only thing in the museum that I had no idea what it might sound like. Because it works in a way no other instrument does. No other instrument physically moves around you in space, flying overhead, and that seemed like magic". Inspired by the Chinese pigeon whistles in the Pitt Rivers Museum, Oxford, Nathaniel Robin Mann decided he wanted to revive the ancient art of pigeon whistling, a tradition possibly thuosands of years old, in which tiny flutes are attached to pigeons in flight. His experience with birds, however, was limited and he needed a bird expert. "None of the pigeon racers wanted to get involved in a music project. Then someone said, 'Well, there's this guy in Nottingham who has a loft made of an old hutch that he straps to the back of his scooter. They call him Pigeon Pete.'"Enter Pete Petravicius, Nottinghamshire ex-miner and steeplejack. A life-long passion for pigeons makes him the perfect trainer to teach the birds how to fly with their unusual musical attachments.We follow Nathan and Pigeon Pete as their friendship, and their understanding of the pigeon whistles grow. From the gloomth of the Pitt Rivers Museum, to the creation of a modern day 3D-printed whistle for Pete's pigeons. Finally, we hear a pigeon's flight described in sound across the sky, creating a haunting, undulating chord cloud, accompanied by Nathan's hypnotic voice, singing songs he has discovered about pigeon culture.Producer: Sara Jane HallAbout the presenters: Nathaniel Mann is a composer, singer and performer. As Sound & Music's Embedded Composer in Residence at the Pitt Rivers Museum and Oxford Contemporary Music, he discovered the world of Pigeon Whistles, and started to explore their potential, supported by PRSF, a foundation helping new musicians make new work. His eclectic projects chart diverse worlds of sound and culture, from bronze foundries and popcorn, to donkeys and Trafalgar Square - each has found a voice through Mann's work. Pete Petravicius is unique in that he is the only man in the UK who trains his birds to return to a mobile pigeon loft. The birds can thus travel across the country, flying in formation and returning to their small motor home/coop. He's also an ex-miner and terrific raconteur who loves his Birmingham Rollers. The Pigeons are cared for in strict accordance to guidelines and regulations laid out by the DEFRA & the Animal Health and Veterinary Laboratories Agency (AHVLA). The use of Pigeon Whistles has been deemed as not causing stress or harm to the birds by independent animal welfare advisors and Pigeon Fancing experts.3D Pigeon Whistles modeled and printed by Joe Banner at Printrite, Nottinghamshire.About the music :The Pigeon Bell Words/Music: Mann - after poems by Mei Yaochen (1002-1060) & Zhang Xian (990-1078) - as translated by Wang ShixiangThe Pigeon Words: Trad.

What is life like for nuns and monks today? With a lack of new blood coming into the traditional monasteries and convents, Bishop Martin Shaw supports some of these aging communities in their painful final days as they are forced to leave their homes. His role as an official visitor, is also to receive the vows of any new nuns and monks joining religious orders, and to hear the concerns and complaints from each community. Sister Giovanna, Sister Clare and Brother Samuel, who are all from different religious communities, recount what life is like for them today. They also share their experiences of dedication over the years - from that first day in the chapel and hearing Gregorian Chant to outside keeping bees and pigs in the orchard, from teaching young children in inner cities to supporting the bereaved in hospitals. We get a glimpse of life in this unique and rarefied world of devotion and commitment, and hear how these communities have changed over the decades. Bishop Shaw has also witnessed these changes, but although monastic life as it has traditionally been lived is unlikely to survive, there are signs of new religious life beginning to emerge within the Church.Produced by Luke Whitlock.

999 was the first emergency telephone number in the world when it was launched on June 30th, 1937. Within the first week, more than a thousand calls were made to the service with one burglar arrested less than five minutes after a member of the public had dialled 999. Impressive stuff. But there were teething problems...In the early days, only those wealthy enough to own a telephone could hope to avail of the service. Exchange room operators complained of stress caused by the raucous buzzers which alerted them to 999 calls. Advancing technology connected with the system began to alter the relationship between public and police. Almost unbelievably in hindsight, the 999 service wasn't made fully available across the nation until 1976.Exactly 80 years after it was introduced, Ian Sansom dials up the remarkable story of our three digit emergency number. Between rare archive, real life-or-death emergencies and interviews with call handlers on the front line, Ian takes a personal look at the evolution of 999 and asks what the future holds for this pioneering British institution.Producer: Conor Garrett.
