1960's Electronica Created By Author Of Dr Who Theme Tune

Delia Derbyshire is responsible for creating the Doctor Who theme tune but she's also responsible for creating an electronic track in 1969 that's way before it's time.

Just today I listened to all 3 parts of the BBC Radio series 'The Definitive History of UK Dance Music' which went back to the early 1960's, but it wasn't until the late 1980's that music like Delia's track appeared. [via]
