I am somewhat dissapointed with this because some years back Harvey had put this night on his web site and I had my brother -the computer geek- somehow save it for me (late 90's?). I played it recently to compare, and the jam alone is 36 minutes long, 3 o'clock in the morning is 20 something minutes long... I don't know why Harveys people chopped it up so much. FYI: The Matrix was a coffie house / club in Frisco owned by Marty Balin of Jefferson Airplane .
