Fired by this thread, I found 'Night Of The Demon' online, downloaded it and shoved it on a usb stick,and (re)watched it on my telly. Still brilliant! And I had forgotten that the comatose 'farmer/murderer' who was in an 'institute for the criminally insane' was none other than a young Brian Wilde aka Mr Barraclough/Foggy Dewhurst! Superb film, still spotting little bits and bobs in it that I never noticed before. And I must have seen it about ten times now! (If not more...)
