Rudolph the Red-Nosed Reindeer

Rudolph the Red-Nosed Reindeer was a popular Christmas song on the planet Earth, originating in the mid-1940s. It became a standard in 1948 when it was recorded by American singer Gene Autry and subsequently inspired many aspects of the Santa Claus legend.

A rock and roll version of the song was popular on Earth in the early 21st century (DW: The Christmas Invasion, Turn Left)
