The song is written by Mack David, Al Hoffman, and Jerry Livingston and is performed by the Mad Hatter and the March Hare at a wacky tea party attended by Alice.

The song is famous for its catchy melody and playful lyrics, which include lines like “A very merry unbirthday to you” and “If you’re born in January or February, Or March, or April, or May; Or June, July, or August, or September, October, November or December, there’s a very merry unbirthday to you!” The Unbirthday Song has since become a beloved classic and is often performed at Disney theme parks and in other Disney productions.
