Beverly Sills was considered one of the premiere sopranos of her time, and you can see this youtube clip of her. She is singing "Sempre Libera", one of the most famous arias from this week's classical pick, La Traviata (Violetta from La Traviata was considered one of her signature roles). This clip is an excerpt from the Muppet Show, in which the muppets put on a show at the "Muppetipolitan Opera". You can hear excerpts from the operas of Wagner, Verdi, and Bizet. The most enjoyable moment is probably 1:30 into the clip, where Miss Piggy (Frank Oz) attempts to outsing Beverly Sills. more ›
