What to do at concerts

I was listening to The Young Turks the other week and they were talking about concerts because of some Michael Jackson clip, in which a grown man was jumping and screaming over him, they had on.  The host, Cenk Uygur, mentioned that he doesn't know how to act at concerts.  It was kind of random.  The other people on the show were giving him a hard time because he is music illiterate (a self imposed title).  

I suppose it depends on the concert venue.  I have not been to many concerts in my day, but I have been to the ones where everyone is sitting down and others where everyone is standing up.  There is also pain in both settings.  Sitting down for a two hour concert, especially in uncomfortable seats, can take your mind away from the music while you adjust yourself when your back hurts.  And then there is standing for two hours.  Very painful on the legs.

When in doubt, be a follower.  Don't be the first one to stand up and get on your chair.  Wait for someone else to do it, and if a bottle comes flying at them from behind, keep your ass in your seat and enjoy the show.
