In a home for retired opera stars, a celebration for Verdi's birthday is fast approaching. Three former colleagues are at hilarious odds . . . not over the section they plan to sing at the celebration, but over the arrival of the newest resident, a diva with whom they once sang the celebrated "Quartet". Jack Hofsiss directs Quartet, by Ronald Harwood. The show stars Paul Hecht, Kaye Ballard, Simon Jones and Sian Phillips.
