Billy Bragg on skiffle, Hokusai's Great Wave, Capt Jack Sparrow returns, Nicola Benedetti, poetry and atrocity

Billy Bragg talks to John Wilson about the music that changed the world - skiffle. His book arguing this, Roots, Radicals and Rockers, is also an insightful survey of post-war youth culture. This was simple music, played on homemade instruments by teenagers - punk before punk. But many skiffle players went on to great things - members of The Beatles, for instance.

The Great Wave , a picture of a huge blue roller breaking over fishing boats, by the Japanese master, Hokusai, is one of the most widely recognised images in the world. An exhibition at the British Museum, Hokusai: Beyond the Great Wave, looks at the artist's latter years, his most creative according to the curator Tim Clark. And contemporary printmaker and artist Rebecca Salter explains the astonishing technique behind Hokusai's work.

This weekend cinemas audiences can see Johnny Depp return as Captain Jack Sparrow in fifth Pirates of the Caribbean film, a role which earned him an Oscar nomination in 2003. But, recently his acting has been overshadowed by stories of his personal life and bad box-office returns - Film critic Angie Errigo comes into look at the career trajectory of the Hollywood actor.

Yesterday violinist Nicola Benedetti was awarded The Queen's Medal for Music, the youngest person ever to receive it. She talks about her musical journey.

Yesterday Tony Walsh responded to the atrocity in Manchester with poetry. He wasn't the first: Shelley wrote The Mask of Anarchy after the Peterloo Massacre in Manchester in 1819, and the bombing of the city in 1996 inspired poems, too. Michael Schmidt, director of the poetry publisher, Carcanent Press, based in Manchester, considers the way poets react to such events.
