Nerves are a good thing, they sharpen up your performance. I agree that small audiences are more difficult to please. I suppose it's harder to generate an atmosphere...

The first song will be the hardest, so choose one that you know backwards, and can belt out! Better still, leave it out completely...

Good luck - though you probably don't really need it!!
