My suggestion would just be to all meet up in the pub opposite Quedgely village hall, making sure we all wear a black arm band to keep Graham happy.
Admittedly I'm biased due to living in Cheltenham, but since it's been the traditional home of the shows it seems an apt place to hold it. Or else Swansea. Hmmm. Of course, someone else could try and hire the hall out for the day. ....@/
