The tune is mentioned as Thirteen floor in the Montreux Jazz Festival's database, as a part of the Ray Charles Meets Dizzy Gillespie concert on 13 July 1978. It was no doubt added to the setlist by Fathead (see below), who also composed it.
A recording, unfortunately, didn't make it to the known releases from this festival edition.
Feasible line-up: Ray Charles - p, Dizzy Gillespie (tp), Hank Crawford (as) and David Newman (fl), Mickey Roker (ds), Kenny Burrel (g), George Duvivier (b).
Fathead's fantastic version (from his album Bigger And Better, Atlantic SD 1505, 1968):
