4) Absolutely. He might have told all those self righteous twits that he was content to be judged by God, but not by them. He was rattled and it was 1966.
5) BlueMeanie's right: Paul pushed the others straight toward Allen Klein, and their resentment at the prospect of having Paul's in laws managing them just might explain why their bullsh*t detectors failed to ever go off in Klein's presence until the Beatles were long gone.
6) I'm going to stick up for "Revolution's" lyrics. I think John was more of a political realist in 1968 than he was three years later. "You say you got a real solution/Well, you know/We'd all love to see the plan" and "But when you want money/for people with minds that hate/All I can tell is brother you have to wait" describes a lot of the hapless, moralizing wanna-be-revolutionary pseuds I knew in college fairly well, and "But if you go carrying pictures of chairman Mao/You ain't going to make it with anyone anyhow," cheap shot though it is, is a pretty good guess at what the source of all that revolutionary fervor really was for a lot of them. On the other hand, "Don't you know it's gonna be all right," unless it's intended ironically, is deluded wishful thinking.
Great idea for a thread.
