my late Godmother told my they did "English country dancing" at school

If it comes to it, I did "English country dancing" at school, some time before I'd ever heard of a 'ceilidh' (barn dances, we had back then). I've never heard of an event called an English Country Dance, however.

we in England do have OUR OWN good culture, which, sadly, is being pushed more-and-more into the background

No, we don't. We have hundreds of different cultures, some flourishing, some reviving, some being kept alive by enthusiasts and some withering on the tree. I think most people here are enthusiasts for one or many of those cultures. But here's the funny thing - the people who are heavily into bell-ringing or playing the Northumbrian small pipes or rapper dancing aren't usually the ones who complain about other people being equally into qawwali chant or gospel music or square-dancing. Enthusiasts for one area of participatory culture generally welcome enthusiasts for other areas, 'English' or otherwise. It's not a problem - the more culture the merrier.

Your insistence on accentuating the negative (in the guise of celebrating something called 'English culture') makes me wonder not only about your politics but, more importantly, about your enthusiasm. What do you actually like?
