Now I know why this record was kept behind the counter when it was released back in 1971. I was only 13 at the time and if memory serves you had to be at least 16 to purchase it. Like I said,if memory serves I'm relatively sure of those facts. It was a long time ago. Anyway,these guys sure seem to be having way too much fun on this night at the Fillmore where penis size seems to be a recurring theme. The musicianship is typical Zappa and the sound quality is great on this 2012 release. I found myself laughing out loud to some of this.
