Strictly speaking, John Henry Hopkins' "We Three Kings" isn't a Christmas carol, even though that's when it usually gets sung. That's because we conflate the two infancy narratives. But this is a song for Epiphany, the day of God's revealing (Matthew 2:1-12).
So, here is a version of it from youtube, which is apparently sung by the Robert Shaw Chorale. Just a note on Shaw, his father was a Disciples pastor, who served the Santa Barbara church I once pastored.
