On this regenerated episode of Impromptu Who, Colin and Brian discuss Jon Pertwee's run as the Doctor and how his tenure can be summed with one word: SUAVE. We also discuss the Brigadier acting more like a grumpy parent with new companion Liz Shaw and how the villains in this serial range from stoic pensioners to melted "Milk Duds" people to tentacle butthole monsters.

Our subject from this episode is Doctor Who: Season 7, Episodes 1-4, titled "Spearhead From Space"
