"I want to go back and look at the roots of this tearing down of politics and of authority in modern Britain. To do this I am going to tell the story of three rather odd men who in their very different ways helped begin it over thirty years ago."
Stephen Knight is one of the three "odd men" mentioned in the above quote. It includes the Joseph Gorman clip from Barlow and Watt. Personally that's something I've already seen. What I've never seen before though is the Horizon series' programme from 24 Nov. 1980 in which Stephen Knight had his brain scanned. There are a couple of clips from the programme at the linked page.
These are not clues, Fred.
It is not yarn leading us to the dark heart of this place.
They are half-glimpsed imaginings, tangle of shadows.
And you and I floundering at them in the ever vainer hope that we might corral then into meaning when we will not.
We will not.
