David Bowie, talking about being a young man in London said that he always used to have a Penguin book in one of his jacket pockets, because the top of it would peek out and make him look more interesting. He said he didn't regret it, because every so often he'd find himself bored and at a loose end and actually read one of them, and read many great books he wouldn't have read if he hadn't been posing.<p>Entertainingly enough, I learned this at the V&A, at the David Bowie Is exhibition.
