"We're Off to See the Wizard" is one of the classic songs from the Academy Award-winning 1939 film The Wizard of Oz. Composer Harold Arlen described it, along with "The Merry Old Land of Oz" and "Ding-Dong! The Witch Is Dead", as one of the "lemon drop" songs of the film. The lyrics are by E.Y. "Yip" Harburg.
The melody's first appearance begins with the Munchkins reciting and Judy Garland echoing "Follow the Yellow Brick Road!", which turns into a group vocal by the Munchkins (while Garland skips and dances along the road) and then segues into "You're Off to See the Wizard".
