"MID-MORNING ON SATURDAY, Berkeley people laid what looked like a
thousand tabs of
sunshine acid on the Angels-- sunshine: it had a lot
of speed in it--and this was being dispersed both at the Angels' bus
thirty yards uphill and on the stage. At one point, 500 reds were
scattered on the front portion of the stage. The Angels were downing
tabs of acid/speed and reds in huge gulps of Red Mountain wine. The more
they took, the more fighting there was."
Rolling Stone, p. 28.
