The "Sign Song" is exactly that: a song with lyrics made up of the names of signs, from "Enter" and "Exit", to "Home Sweet Home". It was first heard on the TV show The Electric Company and its soundtrack album, and was later used on the Sesame Street album Signs!, sung by Big Bird and a chorus of kids (dubbed "The Lost Generation" on the album notes). Some lyrics on the Signs! version are different from those on the original Electric Company version.
