I took this photo from the stage, during a tin whistle guitar solo. Beyond the dancers are tables; there were about 200 people, and they all loved to dance. It was a wonderful first performance for our group, a great alternative to either being background music or a concert performance, with all eyes on us. At the dance, we knew people were listening--they were twirling about--but we were not the focus of attention.
These were fast fiddle waltzes, not "slow dances," though still relatively slow for fiddle music. I did bring my sheet music, but I did try to play without looking at it. Sometimes, I completely forgot what note was next, but often I it was easier to just go with the flow, without the music.
