Well said CB, my thoughts exactly.
Any Arts Centre or commercial enterprise can book most of the guests suggested above, but no-one can buy a CLUB.
A club is somewhere your regulars turn up to not even knowing if there is a guest, come rain, snow, or the call of the hot beach. When you have this, you have a Club!! Make sure you have a membership system, people then feel they belong. It also lets you inform members of forthcoming specials or even, heaven forbid, cancellations.
From the start, establish the idea that everyone pays, even a £1-00 entry soon mounts up and hurts no-one.

We will be in Suffolk next week, will you be up and running or even having a pre-session. If so do let me know details.

It seems you have passed the first obstacle to running a Club, sufficient enthusiasm tinged with a degree if insanity!
Good luck,

Andy
