NTSC Region 0-UK release. Mario Lanza was the most famous tenor the world had ever known. The greatest tenors of the modern era - Pavarotti, Carreras, Domingo and Bocelli - all trace their inspiration back to Lanza who became the first true crossover artist when MGM made him a matinee idol during the 1950s with box office hits such as The Toast of New Orleans, The Great Caruso and The Student Prince.
