That book made my jaw drop many a time. He's very honest, unusually so - even when it makes him look bad. I imagine more than a few people were disillusioned by what he said about his relationships with Pattie Boyd and George Harrison. Neither was the epic love match of legend, to hear him tell it.
P.S. Clapton stayed at the same house (461 Ocean Blvd in Golden Beach) that the Eagles rented when working at Criteria Studios.
