ah, but what do you call a folk club when it is having a singaround, rather than one of its guest nights? is it no longer that folk club?

it certainly appears to be being organised by the same people, using the same website, in the same building, at the same time, with many of the same people in attendance...

and what is the difference between a "singer's night" and a "singaround"? Clearly, somebody needs to time-travel back to the early 1950s and establish a Strict Definition. (Note use of capital letters.)
