First of all , thanx for adding the encore to The Sons set recorded on this memorable night. Not that it really matters , but on the summary for the Quicksilver set , you mention Gary Duncan playing " creepy processed guitar effects " and  "controlled noise" . That was actually John Cipollina coming from side stage and rubbing his guitar on a microphone stand . His unique sound is noticable for the rest of the song . John Cipollina is missed as much as any bay area musician no longer with us . Also , Gary Duncan and I went to the same high school , Ceres High in Ceres , Ca. Long Live Quicksilver and Go Bulldogs . Thanx.
