From Muppet Wiki

The Zizzy Zoomers is a Sesame Street song about the letter Z, sung by the eponymous Zizzy Zoomers, three fuzzy blobs (which featured them changing from red to blue in a few notes). This song took place in a black background.

The Zoomers were performed by Jim Henson, Frank Oz and Jerry Nelson.

Notes

• In later airings of this sketch, an audience cheering sound effect was added at the end of the song.
