What song does the Mad Hatter and March Hare sing at the tea party?

The Mad Hatter and March Hare sing “The Unbirthday Song” at the tea party.

In Disney’s 1951 film, the Hatter, March Hare, and Dormouse celebrate Alice’s unbirthday—a day that is not her actual birthday. The Hatter and Hare present the idea as a reason for celebration, turning an ordinary day into an absurdly cheerful party. Alice becomes the guest of honor even though the occasion is defined by what it is not.

“The Unbirthday Song” was written by Mack David, Al Hoffman, and Jerry Livingston. It is one of the film’s original songs and is performed by Kathryn Beaumont as Alice alongside Ed Wynn and Jerry Colonna, the voices of the Hatter and March Hare. The song is closely tied to the film’s version of the tea-party scene.

Viewers sometimes choose “I’m Late” because the White Rabbit’s song is another famous musical moment, but it occurs earlier and belongs to the Rabbit. “Very Good Advice” is Alice’s later solo, while “The Walrus and the Carpenter” is performed in the Tweedledee and Tweedledum sequence.
