Unexpected find: city prank?

One of the most interesting parts of public information requests from the city (which anyone can file by contacting Donnie Turlington in the Public Affairs Dept.) is that you never know what it will come back with. Sometimes it comes in the form of a stream of emails from Roy Carroll about the noise at Greene Street Club. After narrowing searches by terms and the timeline, there's still frequently plenty of material that isn't pertinent to your search. Take, for example, the email below from four years ago that had nothing to do with what I was looking for in a request that I got back yesterday.
