I'm a big fan of "playing in service to the song", which is one reason The Band is my all-time favorite, uh, band. George Harrison was really good at pistts, his guitar "break" (as opposed to solo) in The Beatles "Nowhere Man", as an example, is absolutely sublime, very reminiscent of James Burton's in Ricky Nelson's recording of "Young World". Kind of, as Marty said, just replaying the melody, but it works really well musically, not virtuosoticly (I know, not really a word).
Marty, Iris' recording of NTTC isn't a "cover"---she wrote the song!
