Country
It occurs to me that the deafening silence one hears when they do the Welcome to Country is that which I used to hear when I was in primary school and they sang God Save the Queen.
Of course there were always a couple of clowns that banged out the chorus, and sometimes even the verses. A mumbling noise that was mercifully drowned out by the drone on the Tannoy, which could have been an organ. Maybe, or the bagpipes, piano accordion, recorder or a harp.
However in the main, the only other thing you could hear was the metaphorical grinding of teeth.
