The Identikit Man
From Tardis Wiki, the free Doctor Who reference
The Identikit Man was a television programme that aired on Earth in 1968. It told the story of a man who returned home from a trip one day to find his identity had vanished. Flora Millrace wrote the score for the programme, using it to detect time distortions on Earth.
Terrorists Turis and Arto used the score from the programme Waterfront Beat to interfere with Flora's score from The Identikit Man in order to draw Time Vortex energy into time distortions on Earth. (PROSE: The Avant Guardian)
