Canadian playwright Michel Marc Bouchard made his breakthrough in 1987 with his best-known play, Les Feluettes ou la Répétition d’un drame romantique (or as we say in English, Lilies, or the Revival of a Romantic Drama). The story, which unfolds as a play within a play, is staged by prisoners who recount the events surrounding a gay love triangle among students at a Catholic boys’ school in rural Canada before the first World War. It’s presented as a staged reading at 7:30 tonight at the Cleveland Playhouse’s Brooks Theatre (8500 Euclid Ave., 216.771.5862). Pierre-Jacques Brault directs. It benefits the Mercury Summer Stock Theatre. Tickets: $10. — Michael Gill
