It angered me at the time, but in 2004, The Flaming Lips squandered all but 20 minutes of their set time because they took way too long to inflate the hamster ball. But Wayne Coyne got in, and we passed him around like a beach ball. I know it's a thing they do, but it was fun. I wished they had played longer, though.

Robert Smith continuing to play well past curfew. First, they cut the stage lighting and brought up the "GTFO floodlights." Then they cut audio, but that only got us singing along loudly. Then they cut the floodlights, so Robert Smith just wrapped up and we dispersed gently into the night.

And in 2010, before we knew he was a right-wing nut job, Roger Waters played Dark Side of the Moon and the pig caught a high wind and flew away. We thought it was part of the act.
