Long detailed version of the one word answer "yes" follows :
It was taped off the television (from the South Bank Show 1983).
The video vault here in the Chateau runs the whole length of a wall and is crammed with all manner of oddities (so much so that every time I open a door something of interest usually falls out)
When we got the notion to run a retrospective of Ken's work (prompted by a recent BBC Documentary).
I had a bit of a root around.
Actually I didn't need to root around much because I've got a nice little niche for Ken's stuff though I was hoping to wait for the totally restored version of The Devils to come out.
Seeing as Warner Bros now seem to want to pretend that film doesn't exist I have pre-ordered the BFI DVD of the UK Theatrical Cut which I have on VHS but it's one of my favorites so I'm pressing ahead and buying it again anyway.
I believe copies of The Planets are to be found in the usual places, to my knowledge it has never received a commercial release.
I mention it here because 99% of what we will be watching will be his cinema works.
Though I hope to get my hands on his television pieces (most of which predate my now ended habit of taping anything that took my fancy for consumption during my present dotage) as soon as finances will allow.
