I just got the MoFi SACD of Piano Man. It may be the first version I've seen that lists the players. My LP back in the 70s had a plain white inner sleeve. My 80s CD had only a track list. Funny thing, though, I also had a book of the sheet music for the whole album. It had several studio pictures. The only one that stuck in my mind was one of Billy at the piano, surrounded by Jackson Browne, Dave Mason, and Frank Zappa. Any one else see this book/photo, or know any stories about the sessions? None of those three are listed. Maybe they just dropped by to hang out?
