Circa 1984 I believe:
Note the shows with a black star next to them: They were FREE to Keystone Card holders! By my count, from 1981-93 I visited the Keystone Berkeley at least 6x and the Keystone Palo Alto and The Stone at least 20x each (Geek Note: Margin of error = +/- 1 or 2 shows). Good times.
THANKS to Chris J. for sharing his archive!
