A group of not-your-typical carolers (who sound suspiciously like the same person multitracked over himself) visit your door and sing a medley of traditional Christmas carols in the wrong tonality (major song in minor keys and vice versa).
Song listing: Deck the Halls (C minor), O Come O Come Immanuel (D major), Silent Night (B-flat minor), God Rest Ye (E major), The First Nowell (D minor), We Three Kings (E major-G minor), What Child is This? (E major/mixolydian), We Wish You a Merry Christmas (E-flat minor). (All songs in the public domain)
