She frequently sang in the USA (Chicago, Pittsburgh, Cincinnati, Houston, San Francisco), Canada (Montreal, Toronto, Vancouver, Quebec City, Edmonton, Stratford), and Europe (Barcelona, Glasgow, Amsterdam, Rouen, Nice). She returned to the Metropolitan 1975-6 to portray Fiordiligi in Cosi fan tutte. She sang the title role in Tosca for CBC TV in 1970 and for the COC in 1972, and was Elisabeth deValois in Don Carlos for the COC in 1977. She sang several leading roles for the Opéra du Québec: the title role in Suor Angelica and Giorgietta in Il Tabarro in 1971, Desdemona in Otello in 1973, and Donna Anna in Don Giovanni, Cio-Cio San in Madama Butterfly, and Alice Ford in Falstaff in 1974. In New York she has appeared in concert versions of such seldom heard operas as Berlioz' Les Troyens in 1972 and Pfitzner's Palestrina in 1973. Her bright lirico-spinto encompasses a wide repertoire ranging from Constanze in The Abduction from the Seraglio to Elsa in Lohengrin, Maddalena in Andrea Chenier, and the title roles in Aida, Salome, and Turandot. Her husband, in a second marriage, is Philon Ktsanes, a Greek-American tenor and vocal coach.
