My sister has social anxiety and I'm afraid nothing I've said seems to make it easier for her. Her worry is that people are looking at her and judging her. I tell her people are too self centered to be worried about you. They are all worried if people are looking at them.
The anxiety is yours, its real, but its groundless. Go out and enjoy the music. If the band is playing there isn't going to be a lot of interaction.
If you have any doubt that you will make it without drinking....DON'T GO. It's just some friend of a friend deal. Don't risk your recovery for something so minor on the scale of social intercourse.
