Few of Maria Callas’s performances were filmed, so these two gala concerts recorded at the Royal Opera House, Covent Garden, in 1962 and 1964 are special. On 4 November 1962, it was before an excited audience that she appeared unexpectedly in a live television transmission of a concert with several other performers. She was in excellent vocal condition, which reassured her fans, who had heard rumors that she was vanishing from the stage to be with Aristotle Onassis or because her voice was failing. Callas sings “Tu che le vanita” from Verdi’s Don Carlo and the flirtatious gypsy girl’s role in the Habanera and the Seguedille from Bizet’s Carmen. In 1963 Callas occasionally recorded for EMI in Paris, but her last triumph was her appearance in Puccini’s Tosca at Covent Garden in 1964. The director was Franco Zeffirelli and singing in the role of Scarpia was baritone Tito Gobbi.
