“Nothing without Paul. . . . .”
True both ways. They needed each other, like sodium and chlorine aren’t salt without each other. Even while the group was still together, they were both terrible as soon as they stopped collaborating.
I agree that their diametric sensibilities made for great chemistry as a band. But Paul clearly didn't need John as much as the other way around.
Actually the Lennon/McCartney songwriting credit was just a formality, something they never changed.
The vast majority of the Beatles songs were Paul songs, or John songs, not a collaboration in the least.
And George Harrison’s magnificent “All Things Must Pass” is by far the best solo effort in the post-Beatles era.
