Girl Replaces Trained Singer 4 Hours Before The Show, Nails The Most Difficult Opera Song

16-year-old Rachele Gilmore only had a four hours' notice that she would sing that night as a trained singer canceled her performance the same day.

Watch how Rachele sings "The Doll Song" from "The Tales of Hoffmann" opera. She was an understudy for Kathleen Kim in the role of Olympia in the opera.

Rachele ended up singing a High A-flat, the highest note to have ever been sung at the Met.
