Nick Cave hates giving interviews. It’s the first thing he mentions in his new book, “Faith, Hope & Carnage”, which comprises a series of conversations between Cave and the writer Seán O’Hagan.  So it’s with some trepidation that Krishnan Guru-Murthy sits down with the post punk legend, to discuss the book, along with Cave’s attending the coronation, the tragic death of his son, his attitudes towards free speech and political correctness, and his journey to find - and define - happiness. With thanks to  the London Review Bookshop, where this interview was filmed.  Produced by Alice Wagstaffe.
