After dubbing the singing parts for the character of Emile de Becque (acted by Rossano Brazzi) in the 1958 film version of "South Pacific", Tozzi spent many years playing the role of de Becque himself in various revivals and road tours of the show, including one at Lincoln Center in the late 1960s. In a return to live national television in 1964, he collaborated with the conductor Alfredo Antonini in the role of Herod in CBS Television's adaptation of Hector Berlioz's oratorio "L'enfance du Christ". In 1980, Tozzi earned a Tony Award nomination for Best Leading Actor in a Musical for his work as Tony in "The Most Happy Fella".
