In her final years as a singer, she sang in "Medea", "Norma", and "Tosca", most notably her Paris, New York, and London Toscas of January–February 1964, and her last performance on stage, on July 5, 1965, at Covent Garden. A live television transmission of act 2 of the Covent Garden "Tosca" of 1964 was broadcast in Britain on February 9, 1964, giving a rare view of Callas in performance and, specifically, of her on-stage collaboration with Tito Gobbi. This has now been preserved on DVD.
