On a Christmas Day in the late 44th century, the Eleventh Doctor heard "Ding Dong Merrily on High" playing from a speaker in Sardicktown while talking to Amy Pond. When Amy asked what it was and he replied "a Christmas carol", he was reminded of A Christmas Carol, and an idea was formed as to how he was to convince Kazran Sardick to save a crashing starliner. Soon after, passengers on a starliner crashing into Sardicktown sang "Silent Night". Amy Pond, a passenger of the ship, projected the singers as holograms to Kazran Sardick to convince him to save them. He was unconvinced, and walked through the holograms, breaking the connection, after two verses. (TV: A Christmas Carol)
