Interesting. I know he wasn't a hardcore lib, but his comment on marxism was on the money. I'm not surprised about the alochol policy, though, I've heard about that from a number of bands. It's okay when they're young and partying, but once schedules are getting messed up because someone ELSE is doing it, and now you're the boss, things change.
Yeah, Zappa loved to say shocking and controversial things. But, I think he mostly believed what he said, knowing that his thoughts were unusual, to put it mildly. lol
