My guest is the singer songwriter and activist Billy Bragg. Billy started his music career in the late 1970s in the band Riff Raff, had a short flirt with the British Army, before embarking on a solo career that has led to twelve albums so far. He is also a tireless political activist for a broad range of progressive causes and groups, including my friends at the anti-racist group Hope not Hate. Finally, he has written several books, including his latest booklet “The Three Dimensions of Freedom”, published with Faber last year. He tweets at @BillyBragg.
