I don't think The Beatles were a rock band more pop/rock and both John and Paul continued their solo career's very much in that vain and style ,they were always to sophisticated musically to be true rockers ?
Politically John had his finger on the pulse of the time, but unlike Bob Geldof he changed very little .
Conversely Paul's greener veggie life style in the 70's seemed at odds with the time , it's funny how green politics are now setting the agenda and it's saving the planet that counts , not stopping never ending wars.
I think the Paul, John war will continue though , it's to good a sport to let drop .
Like BlueMeanie i'm not sure either of them are people worth tearing your hair out over , both have their faults .
Just love The Beatles stop the John, Paul war give peace a chance, only my love holds the other key blah blah
