...one of my favorite live albums (a genre, I must admit, of which I'm generally not fond), Paul Simon's 1974 Paul Simon in Concert: Live Rhymin' (with the South American band Urubamba and the gospel group the Jesse Dixon Singers).
It contains probably my favorite audience/performer exchange of all time.
From a member of the audience: Say a few words!
Simon's reply: Say a few words. Well, let's hope that we're...let's hope that we...continue to live
Cue album's final track, "America"
