" given the public at large the notion that clubs are populated by untalented, socially challenged oddballs.
They don't go.

If the public have the above impression perhaps we should be doing something to change that impression.

So what might work?

How about a truly "open night" (the public is invited in and your residents and members perform their very best stuff - bearing in mind that you will be tending towards the jolly rather than drear)or can your musicians and dancers do something round the Bandstand in the park.(Didn't I read a thread about something in London rececenlty)
I would suggest that if something along the above lines were to occur your tame computer whiz could prepare a pretty flier.

The above is just a thought off the top of my head and someone out there may have already tried something like this.

Dunno might it work?
