Yep. Me too. I also "carpe diemed" on this one. With only 2500 copies it could go fast. And Mosaic masters sometimes go strangely "missing."
As I recall there was only 1 other recording released from this particular engagement. The Artists House LP which was later released on CD (Domino or Gambit, can't recall), with one extra track which was marred by some distortion in the guitar recording (Hope they have corrected that, it's rather jarring, and that's not something you associate with Ed Bickert.) There was an earlier recording released on Telarc Archive "Like Someone in Love" from March '75 at the same club with Terry Clarke on drums instead of Jerry Fuller. And then a '76 recording of the group with Fuller from the Edmonton Jazz festival.
