Colin Baker and Elisabeth Sladen at Kennilworth Agricultural Show 1986

Imagine the thought process in BBC Enterprises, "If you book the Archers for your agricultural show you can have Doctor Who free". Hence a small band of Doctor Who fans mixed with farmers and their animals.

One of the people in the photos below works with a Gecko.

Colin was sporting a few additional cat badges. K9 was snapped at the Backpool exhibition.
