"Boléro"
From Tardis Wiki, the free Doctor Who reference
"Boléro" was a piece of music written by Maurice Ravel. (TV: The Impossible Planet) Ian Chesterton once noted that the people of the year 64 would not have heard it. (PROSE: Byzantium!)
Tobias Zed was listening to it whilst working on the ancient inscriptions found on Krop Tor. The music stopped playing when the Beast contacted Toby through his mind. (TV: The Impossible Planet)
When the BBC World Service played "Boléro" on the radio in 1953, Sylvia O'Donnell remarked in disgust that they would still be playing a series of "light classics" for mutated cockroaches even if the world went up in nuclear flame. (AUDIO: A Thousand Tiny Wings)
