Though I haven't read anything by him for years, I used to be a huge fan of Kurt Vonnegut's. I met him briefly once, in London, at a book signing for Hocus Pocus. His signature includes the familiar asterisk that was, he said, a representation of his asshole, as seen also in this self-portrait below.
I asked him if he knew there was an indie band called Kilgore Trout from Nottingham. He said he didn't, and mumbled something about royalties.
I'll write more, later.
