This is the song that the Who's in Whoville sang in Dr. Seuss' "How the Grinch Stole Christmas".
A very pretty tune that your audience will recognize immediately (even if they don't know it by
the official name). Not too rangy, though French horn needs to be strong with melody.
Remember those cool Dr. Seuss lyrics? "Fahoo fores dahoo dores welcome Christmas, come this way."
