Simon & Garfunkel, of Mrs. Robinson fame, went on tour back in 2003-04. Those of us who weren't able to get the opportunity to see them were lucky to have another chance with their concert recorded for dvd release, now out, titled 'Old Friends : Live on Stage. It's a great show, covering all of the hits.
However, close to it's finish, Paul Simon introduces the next song to audience by casually telling the audience "The last time we sang this song in concert was Carnegie Hall, 1967" The audience, of course, goes nuts.
Simon & Garfunkel are releasing another live album. Called 'Live 1969' it is a recording of some shows they put on in that year. Leaves That Are Green appears on the tracklist. Ooops.
