Man this bought back a bit of a memory.
A few years back, an old school building was being demolished to make way for a new block of classrooms.
Anyhow, I managed to salvage two of the old "radio" system speakers, of the kind that were installed in every classroom, from about 1950 onwards.
The idea behind this system was to be able announce different things to the pupils and teachers, like for Civil Defence purposes.
But the most important function of the system, was so that us young'un's had backing music, to sing the National Anthem to every morning before lessons began.
And what a morale-booster it was!.
I seem to remember a picture of the Queen in every classroom, at the time too.
My, how things have changed.
