I think this is the best thread title ever, especdially in caps lock! lol
On topic though, when I took classical piano lessons we would do auditions every once in a while and I would get really really nervous... not to the point of puking, but I would get really moist hands, which made the playing almost impossible.
So 10 minutes before I was up, I would just go to the bathroom and spend a few minutes washing my hands, taking deep breaths and looking at myself in the mirror thinking "f*ck yeah you can do this" until I believed it
Also, since there were a lot of students that had to take turns playing, we would usually wait alot, and I noticed it goes like this: the more you wait, the more anxious you get, until you get to the point where you don't give a damn anymore and all you want is to get up there and do your thing. So if you plan it ahead of time, you'll be hyped up more than anything.
This is mostly because they took all the fun out of playing in front of people, and was too concerned about making mistakes, not sounding good enough, etc. Ever since I started playing with others (and now my bass instead of the piano), I just feel happy to be up there playing with people who enjoy music as much as I do.
I believe if you all have a hell of a good time on stage, there's a good chance the audience will like it too anyway.
