Highway to Hell by Clinton Walker.
Biography of Bon Scott. The book itself was very detailed and showed the character of Scott well. What I didn't like was how dismissive the author was on everyone else related to AC/DC. The Young brothers were, in turn, stupid, ruthless, tasteless, classless and so on. Managers were invariably incompetent or rip off merchants. On it went - everyone who didn't speak to him in the book was utterly slated.
At least I now know the story of Whole Lotta Rosie
