Welcome to Muppet Wiki!
"Also sprach Zarathustra" is a tone poem by Richard Strauss, composed in 1896 and inspired by Friedrich Nietzsche's philosophical treatise of the same name.
The piece is quoted at the beginning of the "I'm Gonna Always Love You" music video.
In a 1992 episode of Sesame Street, Telly is awed by a large 11 in the arbor, its magnificence underscored by Strauss' music.
In a reference to 2001: A Space Odyssey, the music plays in episode 211 of Muppets Tonight as the show's writers go crazy over a monolith.
