It's about time for Who's Round, Toby Hadoke's Doctor Who 50th anniversary quest to get an anecdote about every single episode of Doctor Who to date. In this instalment, Toby is down the line to Scotland to talk to a key figure from the Eighties.

It's on Skype so forgive the quality but it's worth a listen as Toby has a detailed chat with a director who has crossed paths with every classic Doctor in one way or another. Subjects under discussion include emergency casting, nearly blowing up a mouse and, of course, John Nathan-Turner.

Nominated charity: Marie Curie Cancer Care
