I've always had the point of view - good one if true, wow, pulled that off for going on 60 years soon. Wow, imagine being as good as the living Paul is and never getting your own credit for it.
Seriously, given the tension in the band with not touring and all that was going on, how come there never has been any theories of one or more of the other boys being responsible for killing Paul? Terribly convenient that it was a car crash. If the three of them plus Sir George Martin and all the surrounding caste of many never said a peep, they all must be suspects, dastardly bunch.
