WELL...
Ken, I do hope you have a good time. Not sure why you are worked up...maybe you're just excitable as you read. Do your best to relax about your shows...generally not a good idea to work up a lot of negs as you may find yourself walking in the door that way...and with that, you may not have such a great time.
Seriously, as most have mentioned, one generally doesn't find themselves amongst anyone other than the usuals you will find @ a concert of this genre. Best to chill a little...no need to go in with guns blazed to ready.
Oddly, last Stevie show I went to there was a fistacuff...next thing you know metal chairs were flying!
Two shows for the price of one!
peace
