Crowd surfing at a classical music concert

Dr. David Glowacki, a Royal Society Research Fellow, has gotten quite a bit of press recently for growing "over-excited" at a performance of Handel's Messiah, which led him to start lurching from side to side, raising his hands in the air, whooping, and finally attempting to crowd-surf. At that point, other audience members forcibly ejected him from the concert.

Apparently the director of the performance had encouraged the audience to "clap or whoop when you like" before it started. And Glowacki took him at his word.

Actually, it sounds to me like Glowacki was purposefully trying to be as obnoxious as possible in order to satirize the director's attempt to get the audience more involved, because Glowacki later said, "Classical music, trying to seem cool and less stuffy, reeks of some sort of fossilised art form undergoing a midlife crisis.” [independent.ie]
