After Prisoner Zero escaped from an Atraxi extra-dimensional prison, the Atraxi hijacked the electronics of Earth to broadcast a warning ordering Prisoner Zero to vacate or "the human residence will be incinerated". A Leadworth ice cream man was confused when his ice cream van speakers played the Atraxi warning instead of "Clair de lune". (TV: The Eleventh Hour)
