I'm not that flashy in private; I'm usually pretty reserved. But on stage, it's about not being afraid of anything - of anyone judging you. It's one place you can be free. So why not sing as loud as you can, hoop and holler and jump around? A show is a moment. When it's done, it's over. I find that extremely liberating.
