i was literally directly behind the sound techs, and when everyone started climbing to the top of the pavillion, the security and undercovers came running over and trying to pull people down, and the sound guy started yelling at the cops to knock it off otherwise their tent was going to fall on the equipment. he was right in their face, it was pretty funny.
i dont know if everyone noticed this, but towards the end when the band was making all those broad gestures and not playing anything (?uestlove was waving his cymbols around and stuff) the sound board actually lost power for a few minutes due to all the shenanagins. then when he said "can you all hear me" that was right after the sound came back on. it was pretty crazy.
