It's been a long time since we did a Doctor Who Family Tree episode.

These are episodes where we find people with Doctor Who connections, working together on other projects, and here, we focus on 1984 BBC children's drama The Box of Delights.

It starred Patrick Troughton, with a number of noteable Who alumni working on it too, most notably composer Roger Limb.

Kenny is joined by Roy Gill to discuss their love of the show, and Chris Chapman, who has produced a new documentary on The Box of Delights for the 40th anniversary blu-ray, joins them to talk about it.
