The true story behind blockbuster film Jaws, Benjamin Zephaniah, Catherine Cohen's cabaret

Live from the Edinburgh Festivals : Ian Shaw, son of actor Robert Shaw, discusses his play, The Shark is Broken, based on Jaws. Using his father’s diaries, it’s the story of how Shaw, Roy Scheider and Richard Dreyfuss are tortuously confined together on the boat Orca while filming - enduring endless delays, studio politics, foul weather and a constantly broken mechanical shark called Bruce. The show's getting five star reviews - they’re going to need a bigger venue.

Benjamin Zephaniah is one of our best loved poets, despite his avowed rejection of the establishment. Ahead of his appearance at the Edinburgh International Books Festival, he performs his poem White Comedy, inspired by a TV interview he saw with Muhammed Ali as a young boy.

With the vogue at this year's Fringe for confrontational, confessional shows based on artists' personal trauma, we talk to two performers about how they look after themselves and their audience. Artist and writer Scottee’s show Class confronts the gulf between his working class upbringing and that of his Fringe audience, while performance artist Demi Nandhra's Life is No Laughing Matter explores her relationship with depression.

And we’ve a song from American comedian Catherine Cohen whose sold-out show The Twist? …She’s Gorgeous is winning plaudits for its fast-paced wit and blistering candour on the lives of modern women.
