The sweet strains of a Puccini aria cut through the Saturday night clatter of the busy Italian restaurant in New York City, but it wasn’t coming from the aging voice of the Sicilian baritone who was hired to belt out favorites like Funiculi-Funicula. It was a soprano whose crystal clear voice filled the room. Within moments all the ambient noise came to a halt. Diners stopped eating and talking, busboys stopped clearing tables, the cooks even came out of the kitchen. Singing on the tiny stage was the skinny moon-faced waitress from Ohio.
