Group think.

Having no interest in contemporary music, names like Kanye West mean nothing to me. But I must admit I was fascinated to hear—true or not—that he commanded his audience to stand, including the wheelchair-bound fan. I can't imagine following the orders of any pop entertainer, especially after paying a fortune for a ticket to his concert (a term I still find comical). I'm not surprised however since I have noticed today's audiences are desperate to be part of the show, whether it's standing up, waving their arms, or calling out unwelcome comments to comics like Bill Maher. It's rather odd that at a time when everyone claims to want to be an individual, they are so quick to take part in a group action like the wave or a chant.  I guess if you can't get your fifteen minutes of fame on your own, you're tempted to go to somebody's star vehicle and steal some of theirs.
