Here's another take on the whole George/Pattie thing, from Tony Bramwell and his book Magical Mystery Tours, My Life with the Beatles:
"He (George) became very private...unlike Pattie who wanted to have fun---lots of it. It was unfortunate that she was a flirt. I'd often be at a club and there she would be, surrounded by any number of the dozen virile young rock and rollers...I never asked her where George was, because we all knew that he was at home...But she was never mean...or spiteful. She was just so young and not ready to settle down in suburbia.
"Sometimes, when we were in the studio, George didn't seem to care who heard him anguishing, tearfully begging her to come home. It was embarrassing having to listen to this. And it was even more embarrassing for me to see George, my old Liverpool mate who'd always had all the girls looking at him...since he'd been about twelve, on the end of the telephone, acting like a lovesick calf...as he pleaded with Pattie on the bar phone at whatever club she happened to be...She was his first big love and he couldn't stand the pain. In the end, being excessively worshipped, and being the worshipper, were too much for both of them---she wasn't for him. She ran off with Eric Clapton."
