The Frazzletones
The Frazzletones, a backup singing group of monsters, appeared on Sesame Street in 1975 singing the song "Frazzle" with Frazzle himself. The song was released on the album The Sesame Street Monsters!.
The Frazzletones were performed by Christopher Cerf, Richard Hunt, and Jerry Nelson. The monsters in the group are the same puppets used for the Aristocrats: Maurice Monster, an unnamed purple monster and the early version of Harvey Monster, but with a yellow wig and glasses added (similar to Little Chrissy).
