It’s a community party. It’s a mystery. And it’s a delicious farce. Welcome to the next Cocktails, Canapés, and Comedy theater production, courtesy of the Northport Performing Arts Center. The two-act play Unnecessary Farce involves two cops, three crooks, eight doors and plenty of laughter. The plot revolves around a corrupt mayor who is meeting with his female accountant in a motel, while in the room next door, two undercover cops wait to catch the meeting on video. There’s some confusion as to who’s in which room, who’s being videotaped, who has the money, who hired a hitman and why. Plus, why does the accountant keep taking off her clothes?
