I'd like to know more about the background to this story. There really isn't enough information, and I can't find it on the BBC news site now. Morris dancing itself isn't anti-social behaviour, but a particular group of morris dancers (or some individuals amongst them) could well have been behaving antisocially some of the time. Heavens, they might have been drinking...

Without a permit?
Morris dancing is specifically exempt from pub licensing regulations, but I suppose there might be local bye-laws applicable to any kind of street entertainment.

As I said, not enough information to make sense of this.
