Public relations legend Howard Rubenstein made his Metropolitan Opera debut Saturday in the season premiere of Puccini’s “La Boheme” (pictured above during Thursday’s dress rehearsal). Reliving fond memories of being a walk-on in operas during his college days in Philadelphia, Rubenstein appears as a “super” in the famous market scene in Act 2. Since establishing his firm in New York City, he has continued to be an opera fan. He and his wife, Amy, have subscribed to the Met for more than 50 years. Rubenstein says, “I’m thrilled to retake the stage in this wonderful production and to be part of the Metropolitan Opera while it is undergoing such an exciting transformation and is attracting new audiences through great new productions and free programs.”
