Unto us is born a son King of choirs supernal See on earth his life begun Of lords the lord eternal Christ, from heav'n descending low Comes on earth a stranger Ox and ass their owner know Now cradled in a manger This did herod sore affray And did him bewilder So he gave the word to slay And slew the little childer Of his love and mercy mild Hear the Christmas story O that mary's gentle child Might lead us up to glory! O and a and a and o Cantemus in choro Voice and organ, sing we so Benedicamus domino
