FWIW, this session is currently available on this Gambit CD:
The liners identify the session as recorded at P.J.'s in Los Angeles in Summer 1965, and also acknowledge that it was originally released on Emerald (the Amazon description also identifies the original title as "On Fire"). In addition to the 7 PJ's tracks, the CD also includes a track recorded in Denmark in 1969 ("Medley: Manha De Carnaval/Samba de Orfeu"), 3 tracks recorded for Swedish television in 1973 ("Blues", "Basie's Blues", and "The Shadow of Your Smile"), and a 1969 track recorded at Ronnie Scott's that also features Kenny Burrell and Grant Green ("Blue Mist").
