Paul was always a kick-off rocker, strong vocally, and was as good or better than anyone in his day. He was pushed into playing bass when Stu died and took it to another level. I remember Playboy magazine always listed the best rock musicians annually and Mr. J.P. McCartney was usually, if not always, listed as the best all around bass player.
im looking for the live record where Lennon goes wild, playing the organ with elbows. i think it's from live at Shea Stadium but the whole performance not available on YT
If you haven’t found it already you can look up the shea stadium performance on dailymotion and it is the first song that it shows even though it was the last song they played at shea
