Weird and wonderful! The produce of Stanshall's mind will not be to everyone's taste and you either get it or you don't. I suppose it's fair to say that it would tend to appeal to people of a certain age who were reared on the surreal humour of the late 1950s to mid 1970s.
This is a film that bears watching closely again and again. Packed with detail and references that might be easily missed on first viewing. Just for the record, I can assure prospective viewers that people similar to Sir Henry and almost as weird, actually exist in parts of England.
Some of them are friends of mine.
