I don't really care who played what when. Kaye and Jamerson are both towering legends in my mind. JJ had more hits, but Carol played on more records - 10,000 by her estimate, and that's entirely believable considering how many years she was doing it before retiring.
Funny we'd debate which session players were on a record, but have no problem accepting that Ringo was the Beatles' only drummer. The important thing in all this is that I've been incorrectly referring to that instrument as a "guitar" for all these years. I wonder; is "axe" still acceptable?
