Will the Arse Worshipping take place on the night of a Full Moon???
There is a good beer garden at the Dysart Arms in Bunbury, Cheshire.
You could hold it at Nether End (near Bakewell [if you don't mind the Tarts]), but it is probably best to avoid Nether Wallop (Hampshire) and Nether Padley (also near Bakewell). Just name the place!
Quack!!! GtD
