When PSY, the singer of Gangnam Style fame, declared on May. 4 that each of his summer concerts required 300 tons of drinkable water, he probably didn't expect a controversy to erupt a month later.

He was on the popular TV talkshow Radio Seuta 라디오스타 (Radio Star) to promote his upcoming summer tour, suspended for the last two years because of Covid. "At concert venues we mobilize water mains and even water trucks," he said. "All that water costs a lot of money."

Given the Korean name Heumbbeoksyo 흠뻑쇼 (translated as "The Totally Wet Show"), his summer tour, which started in 2011, is famous for liberally spraying attendees with water and routinely sell out.
