At one Folk singaround that I used to attend there were a small group who spent the time when others were singing just chatting and laughing amongst themselves, while sitting within the group. They had a very limited number of songs that they would perform week after week, none of which could really be said to be folk, and obviously weren't interested in folk music.

I eventually got into the habit of using the time when they were performing to go the the loo or order drinks at the bar. This upset them to the degree that they gave the club organiser an ultimatum - she goes or we won't come again. I continued to go to that session but they, unfortunately, didn't carry out their threat.
