"Monster Lullaby" is a song from the 1975 album The Sesame Street Monsters!. The lullaby is sung by a mommy monster (voiced by Marilyn Sokol) to soothe her son's fear of a nice little girl. The mommy refers to her son (Richard Hunt) as "little junior monster" and "baby monster." It was later performed on Sesame Street by Herry and Rosita to their dolls. (EKA: Episode 3835)
