Cippolina could really play. Quicksilver was one of the big three S.F. bands, along with the Dead and the Airplane. (I have the poster for Bill Graham's first New Year's Eve show featuring those three bands, 9:00 p.m.-9:00 a.m., with breakfast for $4!)
I remember when John was a regular after-midnight fixture at the Dead's NYE shows at Winterland. Those were the days, my friend.
