SqueezeMe, your mistake with the date reminds me of something that happened around the time of the original release of the film Zulu back in 1967(?).
The film begins with Richard Burton reading out a message from South Africa to London, back in 1879, telling of the British defeat at Isandlwana.
The recording of Burton's speech was played on the radio. My grandmother heard the broadcast but she thought that was listening to a contemporary news item, and got the phone to anyone how would listen to tell them of a terrible massacre of British troops by Zulu warriors.
