I would also add, I believe "All My Lovin" was the best pop song ever.

Not just a knack for lovely melodies. He could also write songs with some kick to them: Back in the USSR, Helter Skelter, She Came in through the Bathroom Window (one of my faves--an early stalker song), and Got to Get you into My Life, one of the best horn sections on any Beatles song! I think he hit the right Stax/Memphis sound note with that song perfectly.

Sure he wrote a lot of drivel. So did Lennon. But we should all have such problems, looking at a life of music output that McCartney has had.

And as to those lovely melodies, he did it again with Jennie Wren. So you can't write the old man off yet.
