I became a fan in 1976 at the ripe old age of 16 but didn't get around to seeing them until their very last show at the Old Waldorf (a club that no longer exists) in San Francisco in 1980. It held about 280 to 300 people all told and I do remember that we were only three tables away from the stage. It was a tremendous show! They did announce that it was to be their last show for both the tour and the band and, while this created a momentary atmosphere of sadness, it was made up for by the euphoria of their performance.
I don't recollect the exact set list now but do recall that they played a highlights version of some of the material from Octopus and also performed one or two numbers from The Power and the Glory. The bulk of the material was from Civilian (which they were promoting at the time).
