Ya, all the conflict seemed to be between Paul and George. I can see Paul's perspective as well as I think he seems a little more passionate about the music and wants to put in the effort. I'm guessing they became somewhat listless without Epstein managing them and Paul was probably trying to fill that void.
I was surprised at how civil they were through their disagreements. I guess it could be the cameras and extra people around but they seemed to keep their cool very well.
