An opera singer features in the song "Music of the Street" in episode 4081 of Sesame Street. Miles and Gabi are trying to illustrate to Rosita that everyone has a different way of talking that makes them sound unique. This woman appears to demonstrate that some people speak in song. She also appeared during the song "Everything's Coming Up Noses."
The puppet had originally been used as Big Head in the Muppet Meeting Films. In the film "How to End a Meeting," Big Head dresses as an opera singer (wearing the same viking outfit) to distract an overly long speaker and effectively end the meeting; a play on the proverb "It ain't over till the fat lady sings." The puppet would later be recycled as the Blimp in Statler & Waldorf: From the Balcony.
