Shambles, in answer to your original question: Just try it and see what happens. It seems that some parts of the UK are a lot less flexible than others on this law.

I was in Norwich last week and I gathered that sessions are moving from pub to pub and are pretty well being driven underground because of the situation over there.

I do not know what the reasoning behind this law is but it seems ridiculous to me. I have never known a group of folk players get drunk and start fights in a pub...
