To Perform Or Not To Perform?

There's a party coming up and there's going to be some performers, some jamming and the question; do I want to play? And if I 'play;' what do I play?

I've only played for an audience (of more than three or four) once before. It was a New Year's party and I played with other people for a couple of songs; one of which I sang. So, not much crowd experience. That's my problem; I'm a big wuss when it comes to performing for others. I tend to avoid the possibility.

Also, I have no real idea what the setup is going to be. Is it actually going to be that you get up in front of a bunch of people and do a song, or is it going to be like a big song circle and people play together etc., etc., I have no idea, and I don't think the party organizers know either, so anything could happen.

I'm considering practicing a couple of things, just to be ready...in case...

Unless I decide to chicken out and not even take a guitar with me.
