Sporting event singing is not unique to the Anglosphere nor to Britain specifically.
It’s simply that our culture takes it to a higher dimension.
Listen no further than this exhibition of one football or soccer anthem in full-flourish. Remember, here you are seeing and hearing a 95,000 Australians singing an English football anthem, in a sport less popular there than cricket, Australian Rules Football, rugby and rugby league.
Cultural cousins in full embrace.
It’s palpable. It’s alive.
