Always make sure all buttons and zippers are done up, then you wont have exposure problems.

I suffer from stagefright in inverse proportion to the size of the audience: the bigger the audience, the less stagefright and the bigger the buzz; the smaller the audience, the more intimidated I get. The critical mass seems be be approaching about 100 people, but it's more of a visual thing, rather any any actual count. the distance away from the audience seems to be involved too - not too close, and not too faraway. I also was brought up as an ensemble player rather than a soloist - so when doing a solo, the bigger the audience the better.
