Though their production of A Christmas Carol never was produced on Broadway, it's had a bit of a life in comunity theater. This number is sung by the Cratchit Family. It's performed here by Sheldon Harnick, along with his wife Margery Gray (who had a successful Broadway career, including the show Mr. Wonderful that starred Sammy Davis Jr., and oddly enough had music by Jerry Bock before he teamed up with Harnick), and Leigh Beery, who starred as Roxanna opposite Christopher Plummer in a musical adaptation of Cyrano de Bergerac. (She comes in at the 1-minute mark. Margery Gray follows her.)
This comes from the wonderful CD I've posted several selections from. Sheldon Harnick: Hidden Treasures, which you can find here.
