It´s curious, don´t you think? Paul and George were schoolmates, they lived nearby, took the same bus...they had all the necessary to become best friends but suddenly John appears. Paul has always said it, he felt just like John was his other half ( musically speaking, of course). He always remembers and talks about songwriting with John, exchanging musical ideas, musical experiences, they complement each other. But what about George? I think is a matter of personality. Paul is a person who loves parties, money, being famous, stay in touch with Royalty, to socialize and George hated all that.
When Beatles split Paul missed to death stay with the others but, you know, money issue was in the middle ( and also "you-know-who") but couldn´t just let it go. On the other hand George NEVER missed being a Beatle, maybe sometimes. Everytime, on every show that Paul performs a Beatles´song he´s saying "oh how I wish to go back in time, play with the other guys" and George not so much.
Paul is more a musician, he has an everlasting talent, he can compose from a hard rock theme like Helter Skelter to classical music. George was more rocker-style, more folk, he´s the only one who can mix rock with indian music and make it sound great (remember Paul´s attempt, Riding into Jaipur? Never the same thing).
Well, I must say I identify the best with John and George, but I also LOVE Sir Paul. I agree, I always cry everytime I hear Paul talking about the others with so much tenderness, I LOVED the Paul and George´s hug on Real love. I LOVED when he performed Something and All thing must pass on his tours, I LOVED Paul´s performance on the Concert for George.
And what about George? He reunited The Beatles in 1987, don´t you remember When we was fab video? The walrus (Paul)was there!!!!
