Most of the bass on the Abbey Road medley is either John or George on a Fender Bass IV. Might wanna try a different example to showcase your absolutely audacious claims about Sir Paul's abilities. Seems like your currently experiencing a Jazz and/or classical music snob phase and you believe your music to be superior just because it can be more accurately described and analyzed by mere words. Talking about music is like dancing about architecture; if you are a true musician/music lover you will one day embrace that fact and realize that perfection and exactities are nice, but absolutely not required for someone to be a master of his/her craft.
