Madame Schwartzhead

Madame Sworzet is a lady opera singer who appeared on Sesame Street.

In one sketch, she sings solo about whenever she doesn't know a certain word, she sounding it out until she blends it together to form the word sound instead of asking Bob, Big Bird, or The Count to tell her what it says.

In another sketch, she sings about front and back to the tune of Blue Danube with a Pumpkin, Green, and Purple back-up singer. Her voice is performed by Marilyn Sokol.
