Heigh-Ho was written by Frank Churchill with lyrics by Larry Morey for Walt Disney's Snow White and the Seven Dwarfs, released in 1937 as the first American animated feature film. In the movie the Seven Dwarfs sing it while marching home from their diamond mine, pickaxes over their shoulders. The tune became one of Disney's most enduring songs, played in theme parks and quoted across television for decades. Online it survives as cheerful shorthand for clocking out, reused in workday memes, vlogs and montages.
