I grew up with the voice of Mario Lanza always being played at my home. The tenor from South Philly became a Hollywood star, giving up a career on the opera stage.
He did sing in an opera only one time – yep in good ole New Orleans.
Here is a picture of Lanza in his dressing room on the night of his professional operatic debut (as Pinkerton in Madama Butterfly), New Orleans Municipal Auditorium, April 8, 1948.
My grandmother was in attendance that night and always said that the label that his voice was not big enough for the opera house was completly false. His voice soared over the entire house that night and was beautful.
