Here in Seaforth Kenwick/Gosnells in West Australia is the Acorn Theatre, which is officially the smallest theatre in the world [Guineas Book of Records]
It has now the seating capacity for 28 patrons.
They lost the tittle for  a couple of years at one stage, because of a theatre, some where in Italy. Which was a converted Pitza shop holding about 23 patrons, but it was closed apparently because it?s owner wanted to make more dough!
The Acorn has been around  for a lot of years & still going strong.
So Steve why don?t you send you membership out and about individually or in teams all over town, for a set period of say a few weeks to find possible venues.
Bring them all together on a set date, for a brain storm & listing any &  all the possibilities on a white board. Then discuss which ones to investigate further.
I?m sure they will come up with weird & wonderful places.
Don?t discount any place until they are checked out.
Keep the initial list & all the lists from  future forums.
Go back over these possibilities until something pops up!
If nothing else it would be a good promotion & may get the other villagers, also coming up with venues & even boost your membership.
Get them to chase down any joint & see everyone they talk to as a potential lead.
