In the latest part of his Doctor Who 50th anniversary quest to interview someone connected with every single Doctor Who story, Toby Hadoke spends time in the company of four people who all worked on one legendary early story...

Toby is only supposed to be getting one anecdote from each story - but what if four people are happy to speak to him about the same adventure? Well, he is not going to say no, so strap yourself in for a feature-length podcast with a quartet of interviewees who all worked on one particular adventure from the dawn of Doctor Who.

Nominated charities: Red Cross, Mind, Cancer Research, YMCA
