Yeah, SRS, I think Guest confused them too. When I saw that I thought, WHAT? Mario Lanza was never in a movie of TDS! (Shows how much of a geek I am.) BTW, I'd love to act in a stage production of The Desert Song myself. My dream role is Clementina.
I'd also love to be Adah in Naughty Marietta, just for the chance to sing "Neath The Southern Moon."
