As you can guess, the opening of the bar is not quite just as simple as having volunteers.....
For many years the bar struggled to provide beer from the barrel - the result - major losses, because folks just didn't come along to drink it (apart from a feisty mouse, who found that supping the overspills was better than taking steroids to bulk out his muscles).
Also, tastes change - and with the approach of a third public house in the area (The Admiral Rodney, The Talbot at Knightwick, and now The Crown) - all with major investment programmes to make them successful, it's highly unlikely that a regular bar in the Village Hall would attract a client group to make it worthwhile.
So it's a bit more complicated than just somebody being prepared to give up some time....
