Paul was quoted early on (before the Beatles took off) saying that if the Beatles didn’t get anywhere he’d do it on his own. And he certainly had the talent to do it. But being in partnership with John, with George Martin producing and with the contributions from George and a Ringo, helped make Paul and the Beatles bigger than anything Paul could have been on his own.
Once Paul gained in confidence though his tendency to want to control what was played on his songs grew to such an extent that I don’t think he could ever fit in a band situation again. He had the skills to do it all himself and, as you said Loco, he only ever saw John as some sort of artistic equal. He was never going to listen to anyone else on a regular basis. That is a pity because, no matter how good you are, your work can always stand some tweaking. Paul’s ability did show in his consistent success as a solo artist but, as much as I like some of his and the others solo stuff, taken as a whole it’s not a patch on the Beatles work.
