As Foro and I discussed briefly in the poll thread, Under My Thumb is an underrated gem. We also had plenty of Good Vibrations (RIP) talk in that thread.
My Sharona is a funny song. It's great fun to play in a band, especially as bassist. That riff is pure fun to jam. But sadly, no one besides the band really wants to hear it anymore...
In Keith Richard's autobiography, he talked about how he and Mick and Brian Jones would spend hours jamming under the supervision of Ian Stewart, learning how to "weave". I think Wild Horses is one of their best weaves.
