I'm with MMario (hiya!) on this one. It never gets "easier", so much as you get accustomed to it and figure out ways to cope with the stress. Even after years of singing, you can still find that stage fright if you look inside yourself deep enough. Not that this is anything remotely resembling a good idea to do, of course.

You might want to consider hitting the local library for some books on public speaking. In all honesty, while the "performance" is different, the stagefright is the same. What works for one will normally work for the other.

Personally, I was blessed with starting relatively early (22ish). I solved my dilemma by getting staggering drunk before singing. Didn't hurt that I was with a bunch of other folks either drunk or pretending to be so in order to sing "creatively" rather than "well". By the time I got around to needing to sound better, I'd a thick layer of coping mechanism left for when the alcohol haze cleared.

Not that I've stopped drinking for shows or anything - a pint a set, that's all we ask...
