Bring a Torch, Jeanette, Isabella from Hark! Songs of Christmas Volume II
I absolutely love this song. (In case you couldn't tell, I pretty much love all Christmas songs and all Sufjan songs...) You can listen to it here. This is a French Christmas carol from the 16th century. On Christmas Eve, children in the Provence region of France dress up as milkmaids and shepherds, carry candles and torches, and sing this song on their way to Midnight Mass. I love the lyrics, which urge you to tell everyone in the village about this baby, but keep your voice low so little baby Jesus can enjoy his dreams; how precious!
