About 40 years ago someone started a club in a small village near me. They advertised it as a "music club" because they didn't want to put constraints on what was performed, but they came from the local folk scene and on the first night the audience was largely folkies from other nearby clubs.

The exception was a pair of well-dressed middle-aged women. When the first singer got up with a guitar one of them exclaimed "Oh my God, it's a folk club!" and they both got up and left.
