was revived at the Royal Opera, London, in 1966 for Joan Sutherland. On 13 February 1970, in concert at Carnegie Hall, Beverly Sills sang the first performance in New York since Lily Pons performed it at the Metropolitan Opera House in 1943. This opera is famous for the aria "" (sometimes called ""), which has been called the "Mount Everest" for tenors. It features eight high Cs (a ninth, frequently inserted, is not written). Luciano Pavarotti broke through to stardom via his 1972 performance alongside Sutherland at the Met, when he "leapt over the 'Becher's Brook' of the string of high Cs with an aplomb that left everyone gasping." At a 20 February 2007 performance of the opera at La Scala, Juan Diego Flórez sang "", and then, on popular demand, repeated it, breaking a tradition against encores at La Scala that had lasted nearly 75 years. Flórez repeated this feat on 21 April 2008, the opening night of Laurent Pelly's production (which had been originally staged in 2007 at Covent Garden in London) at the Metropolitan Opera in New York, with Natalie Dessay as Marie. A live performance of this Met production, without an encore of "Ah! mes amis", was cinecast via Metropolitan Opera Live in HD to movie theaters worldwide on 26 April 2008. On 3 March 2019, Mexican tenor Javier Camarena also sang an encore of the aria at the Met, singing 18 high Cs in a performance broadcast live worldwide via Metropolitan Opera radio and cinecast worldwide via Metropolitan Opera Live in HD. As a non-singing role, the Duchess of Crakenthorp is often played by non-operatic celebrities, including actresses such as Dawn French, Bea Arthur, Hermione Gingold, and Kathleen Turner, or by retired opera greats such as Kiri Te Kanawa and Montserrat Caballé. In 2016, US Supreme Court Justice Ruth Bader Ginsburg, a lifelong opera fan, played the Duchess on opening night of the Washington National Opera's production. Today, the opera has become part of the standard repertoire. Films The opera was filmed in a silent film in 1929; a sound film with Anny Ondra in 1933 in German and separately in French; in 1953; and in 1962 with John van Kesteren as Tonio.
