Michael Morpurgo, Dr Helen Sharman

Michael Morpurgo joins Aasmah Mir and the Reverend Richard Coles. He describes how stories from his mother, and a decorated soldier from WWI, have inspired his latest novel; the importance of daydreaming and his reimagining of the Nativity. Helen Sharman became the first Briton in space in 1991. She recalls how that experience affected the rest of her life as we countdown the days to Tim Peake's launch. Tony talks about his experience of being homeless for nine months, before being helped by The Connection at St. Martins. We have tracked down last week's mystery muralist: Ron Brocklehurst tells us about his painting in listener Philip Farmer's house. The photographer Derek Ridgers on documenting British youth tribes - from punks to skinheads and new romantics. JP Devlin chats on the sofa with Steph and Dom from Gogglebox. And Hayley Mills shares her Inheritance Tracks. Blue Skies by Willie Nelson, and the theme from the soundtrack to the film Whistle Down the Wind.
