Heinz Wolff hosts another episode of the quirky show, this time from Aviemore in Scotland, where contestants are assigned a canine task. Mountaineer Hamish MacInnes is the guest judge.

In 1975, before working on 'The Great Egg Race', Heinz Wolff hosted 'The Royal Institution Christmas Lectures' for young people, which were televised by the BBC. As a member of the Medical Research Council, he gave six lectures on physiology and other topics connected with medicine, such as advancements in technology and research. These included the gamma camera, infra-red radiation and ultrasound, which were all new developments at the time.
