Hate to burst your bubble, but us yorkshire folk have been doing nude ceilidhs in Doncaster for donkeys years, I played squeezebox for a band last year in march, in sunny Donny. I can assure you the initial surprise quickly wears off and you realise these are genuine and friendly people, although Max our fiddle player had a roving mike and was in the thick of it! Just curious I suppose! I suspect nude ceilidhs have been going on for a very long time all over Britain, if they offer good money I'll gladly play for them again, but come on chaps, you,re really surprised are you?
