"in fact, a wholesale post-modern revivalist fantasy dating back no further than the 1960s whatever traditional precedents might be cited."

As a child, I was exposed to Morris at Folkestone in the mid 1950s. They would dance at various locations - I particularly remember the East Cliffe Pavilion, accompanied by a Hooden Horse rather like the crocodile of Punch and Judy, which scared me.

I remember from a more recent time reading that the way to identify "real" traditional Morris from the other sort was that in the real version, where it was done because local tradition dictated it should be done, the dancers did not appear to be enjoying themselves.

By this token, that particular side might well be more traditional than not being in the Cotswolds might suggest.
