"Dancing of a like kind" - would that include Irish set dancing, for example? If they discriminate in favour of English Traditions and against other minority ethnic traditions they could be asking for trouble. Klezmer Bands and Hassidic dancing...

Then of course there's the traditional jigging doll.

This could be quite entertaining. I suspect that there could well be some flexxibility introduced through the guideliones as they realise how easy it is going to be to make them appear totally ridiculopus.
