The "Amazing Audience Participation Videos" Thread

[LyricalDrug]

Okay, so this is a little random. I think it'd be cool to collect awesome video/youtube clips, of bands/artists, performing live, where the audience participates in call-response style. For example, the whoah-oh-oh-ohs during "Pride" at a U2 show. But, you get bonus points for non-U2 vids. U2 videos are fine, but we all know all those. I'm curious whether any other bands can match or surpass U2's ability in this area. What've you got?

Here's one, for starters... Arcade Fire, doing 'Wake Up' in London:
