 In 1963 they were approached by composer Ron Grainer to record a theme tune for the upcoming BBC television series "Doctor Who".Presented with the task of "realising" Grainer's score, complete with its descriptions of "sweeps", "swoops", "wind clouds" and "wind bubbles", Delia Derbyshire created a piece of electronic music which has become one of television's most recognisable themes.Over the next quarter-century the Workshop contributed greatly to the programme providing its vast range of unusual sound-effects, from the TARDIS dematerialisation to the Sonic screwdriver, as well as much of the programme's distinctive electronic incidental music, including every score from 1980 to 1985.
