John Carter Cash on his musical production The Ballad of Johnny & June

John Carter Cash on how the lives of his famous parents - Johnny Cash and June Carter Cash - have inspired a stage musical which tells the story of the couple's long love story but also tackles addiction head on. As a long-lost portrait of poet Robert Burns by the acclaimed artist Henry Raeburn goes on display, art historian Bendor Grosvenor and art journalist Melanie Gerlis discuss how experts go about attributing a painting to a great artist. While technology can show us detail far beyond the paint on the canvas, will human expertise and discernment always be necessary in cases such as this? And author Benjamin Wood talks about his atmospheric novel Seascraper, which centres the story of a young shrimper in a coastal town in the north of England who dreams of becoming a folk singer, and which has won the Nero prize for fiction.
