song: Still Crazy After All These Years (partially-written)
artist: Paul Simon
performance: The Dick Cavett Show (1974)
writer: Paul Simon

This is an unusual transcription of Paul Simon's performance of an early sketch of "Still Crazy After All These Years" on The Dick Cavett Show (5th of September 1974). The song was eventually released one year later as the title track on the 1975 studio album. This transcription is an attempt at capturing the song at this early stage, when it was still a guitar-based tune. Eventually, it became a piano-based tune, and was transposed from the key of D major up one fourth to G major; pianist Barry Beckett plays a wonderful Fender Rhodes-part on the studio recording.
In this performance, Paul Simon ends before the yet-unwritten bridge section and presents Dick Cavett with a musical choice between two chord changes with which to proceed: the choice of D9-to-G or D9-to-G#m. Eventually, Paul Simon chose something like the latter, D9-to-G#m/e (that is, D9-to-Emaj7), which was then transposed up to G9-to-Amaj7 in the studio version.
