I read a book about him once... wasn't that good. It was written by this guy who had discovered that his uncle (or something), mainly a painter and decorator but a part-time rent boy (I think), was a peripheral figure on that Soho fifties scene and wrote a kind of biography of his life over that time. Basically (reading between the lines) I think it was a few anecdotes stretched out to make a book and it tried to make the uncle a more central character than he was. I did like the story at the start about the main character meeting Bacon for the first time though and him (Bacon) being introduced as a painter, and the uncle, having no idea who he was, said "Oh really, me too".
