Paul writing a song for the Beatles to perform in their last recording sessions about Klein is about John, George and Ringo. It’s inescapable. Paul wouldn’t be singing about Klein if the other three hadn’t demanded he manage them. By all accounts, hiring Klein split them up as much as anything. You really think Paul can write a song about that, called “You Never Give Me Your Money,” and that the other three don’t take any affront to it at all, even privately? People who are already at their wits’ end with each other don’t work like that. It’s not a wonder it was their last gasp as a group.
