Based on the well-known "Happy Birthday" tune, this short piece was originally part of a group of variations by famous composers commissioned for the Philadelphia Orchestra's seventieth anniversary. The occasion included President Nixon's presentation of the Medal of Freedom to Eugene Ormandy. It has since been performed for other occasions, among them several Copland birthday celebrations.
