 Other roles at Covent Garden in subsequent seasons included Musetta in "La bohème"; Giulietta in "The Tales of Hoffmann"; Liu in "Turandot"; Flora in "La traviata"; Butterfly in "Madama Butterfly"; and the title role in the 1963 production of "Tosca".In May 1960 her role of Musetta was described by Evan Senior as "the most astonishing and effective playing and full-voiced singing of the role I have ever heard or seen".She is probably best known as being the substitute Tosca in Covent Garden's famous 1965 revival of the 1964 Franco Zeffirelli production of the opera.
