SYDNEY, Australia — When members of the Save Chaddy Bowls committee in Melbourne uploaded their parody of the Beyoncé hit “Single Ladies” to defend their club against the threat of a new stadium, they thought they might draw a bit of attention.

But by Monday morning, their video had propelled the three dancers, who range from their late 60s to early 80s, to semi-stardom. Uploaded on Saturday, it had been viewed more than 500,000 times in less than 48 hours.

“I am gobsmacked. I cannot believe it,” said Denise Wallish, 58, who organized the video’s production.

The committee is fighting a local council’s decision to name the Chadstone Bowls Club as the preferred location for a new “multifunctional indoor sports stadium” worth 25 million Australian dollars, or about $20 million.
