 * "The Lion Sleeps Tonight" is a song that has been published under a number of different names. The two most famous English-language recordings were the original 1952 "Wimoweh" by The Weavers and "The LIon Sleeps Tonight", as originally recorded by The Tokens in 1961.   The name for the 1961 version has become arguably the more dominant in English, if only because of the song's inclusion in The Lion King.   Because the song was not credited in the end credits of Rise of the Cybermen, and dialogue only calls it "track number 90", it is difficult to know with precision what the name of the song is in the Doctor Who'' universe — or to know which of the many cover artists is singing the song, as heard in the episode.
