Hard to tell if this instrumental recording is the 1977 Aja album version or a knockoff done for a video demonstration, probably the latter. One thing is for sure, the musicians on the album version and here are stellar. Here was the studio recording line-up for this track, which excludes the lead vocals of Donald Fagen and background vocals of Michael McDonald (note that in this video Walter Becker can be seen playing guitar but he did not play on the album track):
PIANO: Donald Fagen, Electric PIANO: Paul Griffin, CLAVINET: Don Grolnick, GUITAR: Steve Kahn
Lead GUITAR: Jay Graydon, BASS: Chuck Rainey, DRUMS: Rick Marotta, PERCUSSION: Victor Feldman, Gary Coleman, LYRICON: Tom Scott
