The Last Tuesday Society cordially invite you to their Halloween ball for an evening of hellish depravity. This year's main event styles itself after a chapter of Mikail Bulgakov's Master and Margarita, in which Satan hosts a dinner part for his nearest and dearest. Expect naked serving girls, experimental opera and a giant cat called Behemoth officiating. Music provided by the London Gay Symphony orchestra, Tiger Lillies and godfather of electroclash, Larry Tee. Dress code: formal/evil.
