I listened to Paul's basswork during the solo of What Goes On lately. It's superb.
I think What Goes On is great. The guitar work and vocals (Ringo and the backing) are nifty as well. I much prefer this to plonkers like Wait.
The Beatles do country really well, and this sounds relaxed, fun and confident (totally fitting the album).
Maybe on CD it sounds wierd coming after Michelle, but on vinyl it's a great way to kick off side two.
Wait is my least favourite. It sounds lumpy, leaden and uninspired.
