Did you ever stop to think how very odd some traditional carol lyrics are, such as figgy pudding and partridges in pear trees? That's the essence of this lighthearted, tongue-in-cheek carol.
While it could be sung as a unison piece, the real fun comes from singing all three parts. Singing seriously in a choral way will further emphasize the silliness of it all. Your audience will love it. (from Music K-8, Vol. 20, No. 2)
