For many years it has been thought that Protect and Survive included the following announcement spoken by Patrick Allen:
"Mine is the last voice you will ever hear…Do Not be Alarmed"
Although it is pretty much impossible to say with absolute certainty that this was never recorded for Protect and Survive, these exact words do appear on a remix of Frankie Goes to Hollywood’s "Two Tribes", the Carnage Long Version remix recorded in 1984.
There have been persistent rumours over the years that there is also an extended warning in Protect and Survive recorded with the words:
"Mine is the last voice you will ever hear, do not be alarmed." and: "If you mother, or any other member of your family dies due to radiation, put them outside, but remember to tag them first for decontamination purposes."
In likelihood this came from an early version of FGTH Welcome to the Pleasuredome. I have never been able to find this was recorded for Protect and Survive, there also seems no evidence to support the claim Trevor Horn sampled Protect and Survive for Two Tribes, as far as I can tell Patrick Allen was engaged to come back into the studio for FGTH and perform cod-versions of his original lines.
