I agree with that in the fact that John agreed to take care of the album while Paul took care of the film. John brought in Phil Spector and John added his saccastic comments between songs.
In all fairness to Paul, it was his idea to GET BACK by playing a live concert. The film was intended to show the rehearsals of the new songs and then end with a concert. I think it would have been great. Sadly, nobody but Paul seemed to be interested and it showed. John was in the midst of heroin addiction and having Yoko by his side constantly didn't help. George had a bad attitude from the start and was just looking for an excuse to quit. Ringo was working on a film I understand at the time, so his heart wasn't in it. They were under contract to deliver an album and a movie. It was everything Paul could do to keep everyone interested. People want to blame Paul for dominating, but who else was contributing. The good originals on that album were Paul because nobody else was delivering. John had DIG A PONY and DON'T LET ME DOWN. ONE AFTER 909 was an old one. ACROSS THE UNIVERSE was added later. George's I, ME , MINE wasn't recorded during the sessions and FOR YOU BLUE was lazy 12 bar blues. ALL THINGS MUST PASS would have been good but never saw the light of day because George wanted it to sound like The Band and it wasn't working. He of course blames Paul for not helping enough to develop his songs when he would help Paul on his.
Anyway, the point I'm trying to make is that Paul gets the brunt of some bad history. He was the only one that cared enough about The Beatles to keep them together.
