So it is well documented that on Paul's songs, he would instruct George on what/how to play to George's frustration.
On George's songs, take While My Guitar Gently Weeps for instance, how did the baseline come to be? Would George ever dare to instruct Paul? Say, "no, no, I would like you to play it something like this..."
I can't imagine he did or if he ever did would he have received some wrath from Paul?
Back to WMGGW, the methodical base/drum rythym - did Paul likely create it as George introduced them to the song and his vision or did George already have that in mind and led Paul and Ringo to it?
