One of my favorite Muppet Show episodes was with Beverly Sills (a.k.a Bubbles Silverstein). Fozzy thought that she was Bev Sills, a tap-dancing country and western singer. Anyway, Bev and the Muppetopolitan Opera Company sang "Pigaletto." It was a scream!
If I remember the words correctly, this was sung to the tune of the Toreador Song from “Carmen”:
Toreador, en guardé
Toreador, toreador.
This is the only opera that I know
I learned this one in school
We learned the words in French
But even still, we don’t know what it means!
