Yep, seen it (in the theatre no less when it first came out....yes, I am that old), and I do remember loving the music.  If I recall it was Price singing and playing the piano.

Young Malcolm was one of my favs at the time, having just seen Clockwork Orange, and then this one...Wasn't that the movie where he gets slapped in the face at the end....has this startled look on his face, like an instant Kensho?...I think he was musing about what he had to be grateful for, and some old guy slapped some "sense" into him. 

Might need to rent a DVD and see it again.
