In the first set a guy beside me asked me to stop singing because it's distracting him. Then he told me I should stop air drumming and air guitaring because I was in his space. During the intermission he said nobody should ever buy 5 or more shirts at a single concert. Second set, 8-10 people in the three rows around me (including myself) were standing up and rocking out. This guy left during Jacobs Ladder. Why go if your just going to complain about everything.
If I was at a Rush concert, I would be so mesmerized by them that the only way I would be aware of what anyone around me was doing would be if someone threw up. And in that case, it would be the smell that would catch my attention.
Glad you had a good time, Cygnus!
