Jingle Bells

An instrumental version of "Jingle Bells" was played aboard Max Capricorn's spaceship replica of the RMS Titanic as an example of Earth Christmas music. The Tenth Doctor would have heard it after emerging from his TARDIS when it landed aboard the vessel. (DW: Voyage of the Damned).
 * Another instrumental version of the song was included in DW: The Christmas Invasion'', although it was part of the soundtrack, and thus not heard by the characters in-universe. It is often used in movies and television because it is in the public domain and instantly connotes Christmas. The lyrics have not, as of 2009, been heard in a televised episode of any Whoniverse show. Written by James Lord Pierpont, it was originally titled "One Horse Open Sleigh" but popularly became known as "Jingle Bells". The song was recorded by many different singers and bands over the years, with some of the more notable recordings including those by Glenn Miller, Bing Crosby and the Andrews Sisters, and Benny Goodman, to name only a few.
