I think the Panozzos are actually kind of fascinating and would love to get Chuck's take on some of this stuff (has anyone here read his autobiography?).
By the way, after posing this question, I looked up his autobio on Amazon and checked out some of the reviews. I thought this one was kind of interesting:
"If the idea of a reasonably talented bass player who never wrote a single song bitching and moaning through hundreds of pages about the guy on whose coattails he became rich and famous sounds good, then this is the book for you.
"As a lifelong Styx fan, this was a difficult book for me to read because Panozzo clearly distorts aspects of the band's history that are a matter of public record. The hypocrisy of him and the other two classic-era members (Shaw and Young) has been very obvious, and in this book it's on full display. Panozzo acts as if Styx were Led Zepellin until Dennis DeYoung attempted to turn them into Air Supply. Styx, much like Queen, derived their identity through a clever mix of rock, theatricality, and a touch of camp. According to Shaw, as quoted by Panozzo, they didn't want to 'write songs about robots,' which is absurd enough considering that the only song on the album in question that is about that subject is a stone classic, but the current incarnation of the band wrote an entire album (admittedly a good one) about taking a rocket to Mars. Very selective criticism.
"Panozzo has undoubtedly had a tough go of things, but his life just isn't that interesting except for his tenure in Styx, for which he did not sing a note [except for the "America" refrain in "Suite Madame Blue"], nor did he write a note or a lyric. No one expects such a memoir to be objective, but his panning of DeYoung, who wrote and sang all of their biggest hits, including their only #1, comes off as petty after a while. . . ."
Seems like the person who wrote this has a bit of a pro-DDY lean, but the other reviews seems to support the conclusion that Chuck's book isn't going to deliver much about the band beyond what you get on the Behind the Music episode.
