10 episodes into our fourth series and 50 years after he took on the role (remember, Season 7 filming was well underway by late 1969 for a January 1970 debut), we discuss the Jon Pertwee era of Doctor Who.

We discuss each season, along with breakout chats on the Pertwee companions, UNIT, the Third Doctor in other media, such as books and audios, and more.

Before then, as usual, we discuss the past month in Doctor Who which, this time around, includes Jodie Whittaker singing some Coldplay, an amateur version of Mission to the Unknown, and Doctorates all 'round for the cast and crew of The Woman Who Fell to Earth. Were they deserved?

General listener comments from: Shane Gordon (sorry we called you Shane McCoy on the show!), Paolo Damante, Mark Cockram, and Christopher Bryant

Doctor Who Show mailbag emails from: Peter Deadman, David Clarke, Bill McCann, Sheldon Carnegie
