Signs! is a Sesame Street concept album featuring Big Bird, as he takes a trip into the city, and learns about different signs, and what they mean. Along the way, he meets and talks to people in different places, such as a supermarket, and a store with a "Se Habla Español" sign in the window. At the end of his trip, he's afraid he might be lost, until somebody points out the "Sesame Street" sign to him, which enables him to find his way safely home. He then tells Herry Monster about his adventures. "Sign Song" was originally written for The Electric Company.
