Lyrics: [Paul Simon]
Music: Grateful Dead/Paul Simon
A jam by the Grateful Dead supposedly based on Paul Simon's song
"59th Bridge Street Song (Feelin' Groovy)." The best example is played as
part of Dark Star on 13 Feb 1970 on
Dick's Picks Vol 4 at about 18:20.
The connection is pretty tenuous: the chords aren't quite the same, but
Jerry does seem to quote a bit of the melody.
The same recording features on Greyfolded
on the track "73rd Star Bridge Sonata."
