I remember this clearly. I was 7 years old living in Shinfield and we (the family) were eating dinner and this came on the tv. I was really scared
when I heard the voice and still remember it clearly to this day. I know this really happened but am a bit skeptical as it was broadcasted in a
Brittish accent, I can't remember for sure as it was 31 years ago but I think the next day the newcast had mentioned that some 'Hooligans' as I
think they had said had broken into the station and used the transmitting equipment. But am not sure in '77 if broadcasts were recorded or live?
