I was watching Standing in the Shadows of Motown today (great DVD by the way), and I started wondering if Jamerson influenced McCartney.
I know Jamerson influenced just about every bassist of that era but I just had to know specifically! So I googled it of course

and stumbled on this amazing article. Great insight into Paul's playing, it definitely inspired me to learn a couple more beatles songs.
Anyway, I hope you find it interesting. And I'm sorry if this has been posted before.
Cheers!
