From Jenny Everywhere Wiki
Traditional Christmas carols known to the Crew of the Copper-Colored Cupids by 2019, presumably from the Prime Universe, included Hark! The Herald Angels Sing as well as God Rest Ye Merry Gentlemen, O Come All Ye Faithful, Deck the Halls, and We Wish You a Merry Christmas. (PROSE: The Copper-Colored Cupids go Caroling)
