How About 18 Million
In Australia, which has become one of the most totalitarian—and deadly—countries on Earth, and that’s just with Part 1 of the CV1984 Op, 18,812 people united over one non-political song.
If they can do that for fun, why not 1.8 million--or 18 million (which would be pretty awesome and conclusive given Australia's population is around 27 million)--telling the murdical cartel and other authoritarians of Australia to take those jabs and shove 'em, in order to save millions from horrific disabilities and death?
From the YouTube description of the video:
"Our most ambitious video EVER: 18,812 people across 15 cities with 37 musical guests, performing ONE epic song. May we present Pub Choir’s rendition of Toto's Africa. We really hope you like it. How good is it when people work together?!?"
