Thanks, that sounds like something I'd be interested in watching myself. I'll have to see if I can find a digital copy of it.
Though Backbeat didn't really deal with this aspect, I've been thinking a lot about what it must have been like for Pete Best to go through being kicked out only to see them become an instant worldwide sensation overnight. I read he was suicidal for a period of time, and I can imagine how difficult that would have been for him.
