Who sings the original Doctor Doctor song?

Answer 1

The original 1963 radiophonic arrangement of the Doctor Who theme is widely regarded as a significant and innovative piece of electronic music, and Doctor Who was the first television series in the world to have a theme entirely realised through electronic means.[citation needed]

The original theme was composed by Ron Grainer and realised by Delia Derbyshire at the BBC Radiophonic Workshop, with assistance from Dick Mills. The various parts were built up by creating tape loops of an individually struck piano string and individual test oscillators and filters. The Derbyshire arrangement served, with minor edits, as the theme tune up to the end of Season 17 (1979-80).
