The ensemble was created by advertising agency McCann Erickson to sing in a television commercial.
McCann Erickson then got in touch with producer Al Ham, who put together a group of singers for the project (including his wife, Mary Mayo, and their daughter Lorri).
The Hillside Singers version of the song sold a million copies, earning a gold certification from the Recording Industry Association of America.

In 2009 several former Hillside Singers under the name Treehouse 10 released Bug in a Puddle, an album of original children's songs.
