The chant comes from Heigh Ho, the famous work song in Disney's Snow White and the Seven Dwarfs from 1937, sung by the dwarfs as they march home from the diamond mine. In Spanish releases the film is Blancanieves and the refrain becomes Ay Ho, which is how this version circulates on soundboards. The melody has remained part of popular culture through rereleases, parodies and children's media, and online creators reuse the short refrain as shorthand for cheerful teamwork, routine work and a group setting off together in single file.
