Hi Phil. I can see your point; if the club started out as a singers' club, you may well feel that guest nights are not what you were letting yourself in for. Fair enough. But I think it more often works the other way round. And £2 is still modest; I think it's probably roughly equivalent to the 2/6 ~ 3/- we were paying 40 years ago.
KV: sorry if this seems like a hijack; I thought your question was answered early on - we don't think there is a known statistic, but we're guessing that there aren't many of us. That could have been the end of it, but we've taken a slight side-step into trying to determine why that is. But then, have you ever known a thread - or for that matter a discussion or argument that didn't wander round in circles?
