Near West Theatre’s productions are all about participation, especially when it comes to neighborhood kids. They’re bringing the same concept downtown for tonight’s Evening in the Enchanted Cathedral. Spokesperson Sara Radak says the benefit party will take advantage of Trinity Cathedral’s ambiance to create a live-in fantasy. Guests can mingle with characters like the Hunchback of Notre Dame and Beauty and the Beast’s ugly half. They can also purchase keys to a treasure chest filled with prizes. The main event is a short revue of performance numbers from recent New West shows, including “Everybody Rejoice” from last fall’s The Wiz. There’ll be plenty of food and drink too. It all starts at 7:30 p.m. at Trinity Cathedral (2230 Euclid Ave., 216.961.6391). Tickets: $75. — Michael Gill
