Guest baz, well said. The singarounds I go to sound similar to yours, and it's much a social thing as anything else. I think some of the participants just enjoy singing or playing occasionally and have no illusions about how good they are, it's just the pleasure of joining in. I enjoy that as well, but I also regard the singarounds as a good place to 'test' new songs or arrangements before I take them further.

But some clubs are able to provide both the 'social/singaround' get-together as well as the more formal guest night - but not on the same evening, which I think would be a mistake. In other words, I think a single club can provide for both types of evening, but not in combination.
