Douglas Adams' tenure as Script Editor is typified by two things. Firstly, there's some glorious bouts of imagination tied up with strong Science-Fiction concepts. Secondly, the levels of silliness occasionally veer into the unacceptable. Partly this is down to Tom Baker, who by this stage felt untouchable, and his willingness to muck about rubs off on the rest of the cast (including his drinking buddy, Graham Crowden). Doctor Who attracts people who want things to be taken very seriously indeed (begging the question of what the hell they're doing watching Doctor Who), and this approach was a step too far for some.
Clement Graham Crowden was the son of an Edinburgh schoolmaster and attended the Edinburgh Academy, where he won a music prize for singing and made a mark as The Duke in Patience.
