I did some sort of quiz , sometime about 1980, when I recorded the voices of as many school masters as I could and then played them back to see who could guess who the Masters were
I have come across the tape ! It has the voices of all the following staff on it in order ( The numbers are read out on tape)
Hope you can spread it to a wider audience and perhaps keep a copy in the archives !!
