Paul's bass line in Come Together makes the song. It would not be the same song without it. And John was so snotty about his participating. Well, according to Emerick anyway. I also love the way the bass and drums work together in A Day in the Life. It's brilliant. And how about Everybody's Got Something to Hide Except For Me and My Monkey and While My Guitar Gently Weeps?
Here's an article on the evolution of Paul's bass playing for those interested:http://abbeyrd.best.vwh.net/paulbass.htm
I like what the guy says about Come Together:
"A personal note: every once in a while, I wake up in a cold sweat, having just dreamed that John didn't record "Come Together" with The Beatles, instead introducing it with The Plastic Ono Band where he had Klaus Voorman's bass under tight reign. Then I breath a sigh of relief. No, this didn't happen. He recorded it with the Beatles, thankfully, especially Paul and Ringo."
BTW, the bass in Revolution is pretty damn cool too. I know it's not complicated or anything, but it's just perfect for that song. Driving.
