"I've never danced - I won't attend anything in England advertised as a ceilidh (maybe if I vist Scotland I will), but have enjoyed listening to and watching the dancing at festivals in Durham and Northumberland (and can recognise stars, arches, do-si-dos, swings, etc.)."

So you've never been to an English Ceilidh, you don't dance yourself, but you're still going to not only try and define it, but also dictate to the many participants and bands out there about what they ought to be calling it.

Plus ca change...

PS - So what is this dancing you're watching at festivals in Durham and Northumberland?
