I'm sure you're right, Les. It's a bit like the archaeologists' way of explaining their unexplainable finds as 'something connected with ritual'... then, when they find out what it really  is the other explanation fades away!

There are as many explanations of the Morris as there are people doing it - and the fact that so many different traditions come under the 'Morris Umbrella' (I've got one!), it seems daft to try to make one explanation fit all.

The 'Moorish' connection which is supposed (by some) to explain the word 'Morris' seems valid with dancers such as the Britannia Coconutters from Bacup and some Border Morris, possibly Molly, too. It doesn't fit at all with Cotswold or North West, nor does it seem to sit well with Rapper, Longsword et al. Apologies to those whose traditions I have omitted!

Of course, this is just my  opinion...!!
