Silent Night

Silent Night was a Christmas carol that the passengers on a starliner crashing into Sardicktown sang on a Christmas in the 44th century. 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.

Its lyrics included:
 * Silent night, holy night,
 * All is calm, all is bright,
 * 'Round yon Virgin Mother and Child!
 * Holy Infant, so tender and mild,
 * Christ, the Saviour, is born!
 * Christ, the Saviour, is born.


 * Silent night, holy night,
 * Shepherds quake at the sight!
 * Glories stream from Heaven afar,
 * Heavenly Hosts sing Hallelujah.
 * Christ, the Saviour, is born!
 * Christ, the Saviour, is born.

(TV: A Christmas Carol)

Behind the scenes
Technically, those lyrics are incorrect; "Christ, the saviour, is born" actually only enters in the second verse, and not the first.
