I remember getting "Inner Mounting Flame" and "Birds Of Fire"albums when they released and still have them in A condition.
Saw him live at the Pope Joy Hall in Albq. NM in 1978. Stanley Clark opened for him.
(my wife was 8 months pregnant with our first...she was miserable and hated both groups lol....and wasn't real happy with me for talking her into going.)
It was an amazing concert.
I remember during the concert that John broke into a few minutes of solo...it was amazing as if he was just jamming by himself...then he stepped up to the mic and said, "bass player broke a string" and the group kicked in again. Jaw dropping performances that night.
