Some of the folk clubs - like the Lancaster Folk Stir I used to go to in the mid-1960s - started off as folk dance societies dedicated purely to folk dance. They then morphed into folk dance and song and, eventually, lost the dance element completely. I can still remember the main organiser - Mrs. Gladys Parkinson - who seemed to me to be always slightly bemused by the singing that went on!

Not all went through that change in precisely the same way, but Lancaster was a typical example of its kind.
