Comedian and playwright Lewis Black will host the gala that promises cabaret performances by Maroulis (Rock of Ages, The Wedding Singer, "American Idol"), Goldwyn (Promises, Promises; The Exonerated, "Ghost") and Hahn (Boeing-Boeing, "Revolutionary Road," "Crossing Jordan"). All are Williamstown alumni.
Additional performers are expected to be announced shortly. The talent will be joined by young members of the Williamstown apprentice and non-equity companies. Kris Kukul will musical direct.
The gala, which includes cocktails, a seated dinner, silent auction and the cabaret, begins at 6:30 PM.
Jenny Gersten serves as the artistic director of the Williamstown Theatre Festival, which staged the world premiere of Tony winner John Doyle's Rodgers and Hart revue Ten Cents a Dance last summer.
