Wow! Is this new news, Cor?
Sir George Martin is really one of my favorite old guys. It seems as if he's really out to tidy up his life and make it nice and neat before making a dignified exit. He seems to go the extra mile to be fair, and he wants to keep on good speaking terms with his conscience. Bravo!
That said, I don't think it was Sir George so much as Beatle George. I think Pete got a lousy deal-- I'd read somewhere that nowadays you'd have a separation settlement and get a band fixed up for him in advance. I still think Ringo was better for the group. He clicked with them as others have said, considered the other Beatles brothers, and I think they would have self-destructed under the insanity of Beatlemania unless they were four really good friends.
Perhaps I'm doing Pete an injustice. He didn't like to hang with them in Liverpool or Hamburg, not caring to be part of the gang, even though he was perfectly friendly with everyone, particularly John. He might have been able to adapt to being closeted with this "gang of 3" every day of his life for 4 years... but I think it would have been more of a trial for all of them. Interesting.
