If there's a law about how late at night one can make noise, it should be enforced as written or stricken from the books. If there's no law, no one should get shut down for making noise.

Does anyone actually know if there is existing law in this locale about when and how much noise can be made?

It seems clear that trying to make this about culture or Morris dancing is misdirection, on the parts of both the newspaper and some of the people on this thread. We had a party house in our neighborhood shut down some years ago because they made too much noise too late at night. It had nothing to do with whether or not we liked their taste in music.
