Not to particpate in a troll thread... but according to Geoff Emerick in his autobiography of recording the Beatles, McCartney spent hours in the studio after everyone had gone home working out his bass lines by himself, so I don't think that Sir George had that much of a hand in it - especially after Revolver.
Not a troll, really just something that occured to me. Interesting info about hanging in the studio without the others.
