My memory of this may be a bit faulty, but as I recall it the advice included painting your windows white to protect yourselves from the flash, building a shelter in your house by taking the doors off their hinges and leaning them against the wall, and designating one room for the storage of the dead.
It was such an English response to the unthinkable that it was almost risible. Raymond Briggs wrote When The Wind Blows, which I think was meant to lampoon the whole business but instead turned out to be almost unbearably poignant, far and away the best thing he ever did.
Anyway, those days are over. Right? Right?
Maybe not. According to the Telegraph, in the event of a terrorist anthrax attack, a good old-fashioned cuppa will go down a treat. Coffee won't cut it. It has to be a cup of tea.
And so we go on.
What? Oh, the subject line. There was an English actor named Patrick Allen, who turned up in such Brit science fiction B movies as `Night Of The Big Heat' and stuff like that. But he was more famous for his rich, booming voice - he narrated the first Blackadder series, as well as doing countless adverts and voice-overs.
He did the voice-overs for a series of Government nuclear `Protect And Survive' films, and as I remember it (and if I'm wrong please correct me) he recorded a number of public service radio announcements, which would be broadcast in the event of a nuclear war.
For this reason, when Frankie Goes To Hollywood recorded `Two Tribes,' they featured his voice doing some of the announcements on the song.
They must also have got him in to do some bespoke work on the song, because there was one mix, which I only ever heard once on the radio but has stayed with me ever since. Part of it was the band introducing themselves - "I'm Holly," "I'm Paul," and so on - and then Patrick Allen's voice saying, "Mine is the last voice you will ever hear." Chilling.
