It's Doctor Who's 62nd anniversary - hurrah!
To commemorate the occasion, we take an in-depth look at Dr Who and the Spare-Part People (also known as The Brain Drain, but given Big Finish recently did a Third Doctor tale with that title - totally unrelated - we're using The Spare-Part People!).
Originally written by Jon Pertwee and his friend Reed de Rouen, this was pitched around the time of Season 7 to the production office, but never made.
We bring you readings of the full plot breakdown, complete with a Radiophonic Workshop score, and our thoughts on the outline.
Should it have been developed? Tune in and decide for yourself!
