Rudolph the Red-Nosed Reindeer

"Rudolph the Red-Nosed Reindeer" was a popular Christmas song on the planet Earth. A rock and roll version of the song was heard on the radio in the early 21st centuries of both the standard timeline and one created by Donna Noble. (TV: The Christmas Invasion, Turn Left)

Behind the scenes

 * The song became a standard in 1948 when it was recorded by American singer Gene Autry. It subsequently inspired many aspects of the Santa Claus legend. In Doctor Who, the same recording of the song was used for Turn Left and The Christmas Invasion, but the performers were not credited.
 * This is also one of the songs performed by Strax in the non-canon webcast Songtaran Carols.
