By all accounts Paul McCartney is an MLA (Major League A$$hole), even aside from his “Who asked you?” political comments. So if he thinks he saw God while tripping, and considering his formidable ego, chances are he was simply looking in a mirror and mistook the image for Deity. I change stations whenever anything he did post-Beatles comes on the radio. Not so much because of his politics and reputation as an arrogant pr***, but because most of it’s commercial grade crap.
Even Phil Collins can't stand the guy, and that's saying something.
