This link from Mark Ayres tells of plans to issue a CD box set celebrating the 50th anniversary of the BBC's now-defunct Radiophonic Workshop, pioneering in-house department responsible for themes and sound effects across a range of programmes.
Ah, that original version of the Doctor Who theme - described by my godson as "ghosts screaming on a rollercoaster".
Disbanded ten years ago, the Workshop's reputation is such that many people assume it's still in business. The Radiophonic Workshop is a reminder of the days when the BBC had an actual creative culture and wasn't just a services-buying bureaucracy. When Doctor Who finally returned to such resounding acclaim, what was one of the first things the BBC did?
They closed the Model Unit.
