I don't put anything on, but I do become different when I'm on stage. I become a bit more confident, a bit cheeky, a bit more charming than I would dare to be in 'real life'.
Once, when we were performing at an open mic night, most of the crowd were really drunk and lairy, just jumping around. This one guy was being a total rude asshole and eventually fell onto the tiny stage, almost knocking me over, and almost smashing my teeth in with the microphone. Now I'm only a small girl, and I'm normally quite a pacifist, but as he hit the ground, I just got the 'red mist'. I knew he couldn't go unpunished for trying to spoil the enjoyment of the appreciative people in the crowd. So I just did it, without missing a note of the song I was singing - I KICKED HIM IN THE HEAD!
The beauty of it is, it got everybody watching and listening. And they all started to behave, 'cos they knew that if they didn't, they'd be next! And I got a humungous cheer at the end. I've always had a bit more stage presence since that day, and people still come up to me and shake my hand. So, to that guy, who probably doesn't remember what he did that night: THANK YOU!!!!
