Goldsmiths has produced 20 Turner Prize winners. It produced Damien Hirst and the majority of the Brit Art pack that caused such a Nineties sensation. It has attracted some pretty impressive tutors to its fine art department – ground-breaking artists in their own right, in fact. As such, the school is considered to be something of a star in itself.

Billy Childish claims to think only in pictures. But since writing forms as big a part of his creative output as painting, that can’t be quite true. In fact, he’s written a number of autobiographical novels as well as collections of poetry. What’s more, he’s a hugely prolific musician, so I’m sure he means only that he feels a little more comfortable expressing himself through imagery rather than abstract concepts – though obviously, being human, he must do that as well.
