Congratulations :D
And yep to wot they said ^
Take own mic stands, and even more important, own mics - partly because of sound, but also cos you never know what some diseased erk has flobbed into a "used" mic :lol:
And towels, lots of towels... and, unless I had a "costume" that required donning before the show, I used to take a dry shirt, at the very least, for afterwards... there's nothing worse than a freezing get-out when you're soaked to the skin!!
