Let me be a pain in the arse.
Either Morris (and other alleged ritual dance) is just social dancing about and having a laugh, in which case lets leave it at that.
Or, it is very old, possibly of pagan origin and has some probably ritual origin and purpose. This is the line put about by EFDSS, the Morris Ring, Dancing England and most Morris dancers when asked about it.
In which case why do so many sides cheapen a possible ancient ritual dance by performing anywhere, anytime for anybody and often being very silly at the same time?
