I've just finished reading the Pat Patterson autobiography, Accepted. Found in a charity shop in Bangor.
It's very candid and it was interesting reading about his experiences as a gay man in the 50s and 60s.
The book was essentially hundreds of paragraph-long anecdotes. He doesn't go into detail about anything - the Slaughter match is a couple of paragraphs at best, mentions wrestling a bear as a throwaway sentence, mentions not remembering winning the Intercontinental title or even remembering visiting Rio where if you didn't know the story the joke would make no sense.
All in all, an easy read, with some interesting stuff, but don't go out of your way to read or expect in-depth stories.
