I haven't read much of the book but I've a feeling it's special. I felt that rush of excitement like I was reading something fresh and new. It's like seeing old footage (and I'd like to get my hands on his photos and cassette tapes). There's a chapter on the Eagles from a tour in 1980, another on a short tour with JD Souther and there are Joe Walsh bits sprinkled here and there (Joe's a friend dating back to James Gang days). There are b&w photos (several of Joe, one of Don Henley) but they're a bit murky and wouldn't scan well.
Most of the book is about The Who but also the Rolling Stones and the Faces.
ETA: Here's one of his photos (not in the book)
