"Voodoo Child" performed by the Rogue Traders, written by Elvis Costello (well, he wrote a riff sampled in the song), James Ash, and Steve Davis, not to be confused with the song "Voodoo Child (Slight Return)" by the Jimi Hendrix Experience.
Doctor Who fans will remember this as the song playing when the Master unleashed the Toclafane on the Earth in the Episode "The Sound of Drums." (Yes, I'm a nerd. What's your point?)
It is interesting to note that lead singer Natalie Bassingthwaighte (who has since left the band) also appeared in the Australian soap opera "Neighbors." Her appearance was disguised in this video so that the song would be judged on its own merits rather than from a celebrity halo effect. Other notable actors to have appeared in "Neighbors" include Russell Crow, Kylie Minogue, and Dichen Lachman (who is currently appearing in Joss Whedon's "Dollhouse" as Sierra).
