I can't believe I'm responding to something as patently ridiculous as this, but if you want to use the last GE as a bellwether as to weather we keep the singing of land of hope and glory or not (still makes me laugh), more people voted Lab, Lib, SNP than Tory, Brexit and BNP (I'm assuming these are the parties you're suggesting indicate the national mood).
It would be ridiculous to suggest the reason there isn't a big fuck off choir and loads of people singing a shit song in the royal albert hall is to do with the transmission of coronavirus, wouldn't it.
