It didn't transmit in the East Anglia region I just remember the talk on the playground about it........ taking into account that no one in my region would have actually seen it and that it made the talk of the playground it must have been quite a big deal at the time.
I did see years later the C4 hoax about the haunted house with Sarah Greene........... I didn't sleep for a week!! AND I was an adult by then...... gotta love the british humour :)
