Bob...So much good advice here from so many talented people...I'll just add that altho I like a dram or 6 as well as the next person, but for me, before performing, it's definitely cold turkey si, Wild Turkey no.

Also this... I am a singer who plays guitar just to accompany myself. And altho I agree in theory with all the energy manipulation stuff, in practice I was never able to overcome the fear, and--worse yet--the accompanying voice wobbles, forgotten lyrics, muffed chords, you name it. Then I started volunteering at local convalescent and rest homes. Audiences there very mixed, but often pretty distracting, especially in the dementia units. By the 6th or 7th visit, I began to relax. No way to NOT stumble, when dealing with those who's enthusiastic response extends to patting your face, tugging on clothes to gain attention, etc. Pretty soon I began to just smile and go on, when I forgot lyrics, either to the next verse or next song. And was delighted to find that this extended to playing in front of other musicians and friends as well. I NEVER expected to become this easy with playing in public...I couldn't even bring myself to play in front of encouraging friends, without falling apart afterward.

So if all else fails, try entertaining in a place where you know the audience will accept with real pleasure whatever you bring to them. It is very rewarding on all levels!
