I used to do voluntary work at a hospital radio station in South Wales in the early 90's - St Cadocs hospital in Caerleon (as seen on Dr Who current series Episode 1 & 2 and Torchwood), and it was a spooky place, if you imagine a typical Victorian asylum, its wasn't far off from that. We had very strict guidelines on what we could say on the radio - and we couldn't play anything by Madness for starters or any song to do with going mad or losing one's mind. Then the studio would get invaded at random intervals by various characters if we forget to 'lock' ourselves in - they would come in and sit there for hours and stare at you, quite harmless and they seemed quite happy. Anyway, after I got released, er, left they had apparently demolished the studio to make way for new buildings.
