John Lennon disagreed with Paul McCartney on more than Macca's post-Beatles career arc - not the outrageous success part, but the leftwing proselytizing.

John Lennon's last personal assistant said as the musician aged, he got more conservative.  No surprise there, most intellectuals do.   In a new documentary,"Beatles Stories", Fred Seaman tells filmmaker Seth Swirsky Lennon wasn't the peace-loving militant fans thought he was and that he instead argued with former left-wing radicals and was embarrassed by his former stances.

Well, in "Revolution" he was already drawing a demarcation line with radicals who just wanted to blow things up and change for the sake of change, not change for a better world, so it isn't a complete surprise.   

"John, basically, made it very clear that if he were an American he would vote for Reagan because he was really sour on (Democrat) Jimmy Carter," said Seaman.  "He was a very different person back in 1979 and 80 than he'd been when he wrote Imagine. By 1979 he looked back on that guy and was embarrassed by that guy's naivete."

No surprise.  In the early 1970s he ridiculed Paul McCartney's songs but his biggest success came after he aged and made "Double Fantasy", chock full of the kind of stuff McCartney had been writing all along.   With wisdom, Lennon's politics went right and so did his music.
