Delia Derbyshire's electronica JUL 21 2008
Working in the BBC's Radiophonic Workshop, Delia Derbyshire recorded the Doctor Who theme song in 1963 but also came up with a piece of electronica in the late 60s that sounds like it was recorded in the mid-90s.
Ms Derbyshire was well-known for favouring the use of a green metal lampshade as a musical instrument and said she took some of her inspiration from the sound of air raid sirens, which she heard growing up in Coventry in the Second World War.
Update: Derbyshire arranged and recorded the Doctor Who theme song but didn't write it. Ron Grainer did. (thx, kevin & pete)
