I agree. During the LROOE tour, the rule of thumb (from the band) was clear. You sat for the first 7 songs and then it was ok to get up and dance if the majority of your seat mates were up. This tour, it's kind of a crap shoot in that Already Gone is definitely not a ballad, but not a lot of people get up, despite the fact that Glenn says in the intro "It's time to rock a little harder." How do you hear that and NOT get up?!?! There's no winning, though, because you can't make everyone happy. Dreamer and I were in the 5th row dead center for this show and the people behind us were not happy that we were standing for Funk 49 -- definitely not a ballad. On a good note, I didn't listen to my inner demon voice and blast her for repeatedly poking me in the back rather than trying the polite "excuse me" approach.
It's hard to concentrate on enjoying the music and the performance when you are waiting to be reprimanded and scolded to sit down by either security or stodgy audience members -- but I manage to block out the BS and enjoy the show!
