Are you talking about the 19 minute live version? Discogs has it on vinyl and Cd. I urge you to look for the Rhino 24 bit remaster on cd,it has both the studio version and the live version and the sound is quite good compared to the original recording.
An erry story I remember the day I bought it I was at The Habit trying their hamburger for the first time and waiting for my order.
I was reading the liner notes which comes with the cd and look up. Sitting at my table waiting for his order was local weatherman icon from Channel 7 eyewitness news Dr. George Fishbeck. I reconconized him and we talked for a bit then he left with his order.
When he left it dawned on me that his only son was accidently shot with a rifle while in a van driving through La Tuna Canyon and died. Dr. George found solace at this time in his life through self medication which led to him leaving eye witness news. The drummer Ron Bushy of Iron Butterfly disappeared only to be found in the bottom of a raveen 7 years later sitting in his car dead
In that canyon.
