I have memories dating back to around 1980, when I was a card carrying member of the "Eco" Party (a precursor to the Green Party), of
taking part in a demonstration in (I think) the Peace Gardens, in central Manchester, during which we sheltered under a couple of doors leant against a kitchen table - as instructed by a government pamphlet that had been sent to all householders with instructions as to what to do in the event of a nuclear attack, and
the Eco Party hosting a public showing of a film (what would nowadays be called a docu-drama), about the likely outcome of a nuclear attack on Britain, that the BBC had made but decided against showing on the grounds that it was too scary.
My biggest memory of the showing of that film was a survivor of Hiroshima giving an impromptu talk to the audience afterwards, and then, like any true Japanese tourist, taking out his Pentax camera and taking photographs of the proceedings.
I also remember sneaking the film projector belonging to the school I taught in at the time out of school for the showing of the film. I somehow thought the headmaster would not have given me official leave to borrow it for the reason I wanted it.
