Earlier this week, a woman returned to her Kentucky hotel to find "1,000 high school students" had checked in. As Michelle Johnson explained on Facebook, "They had been making quite the ruckus tonight, but then did this to celebrate the start of the Olympics."
"This" turned out to be a multi-story rendition of the national anthem.
The students were reportedly attending the Kentucky Music Educators Association conference; singing the anthem is an annual tradition.
"18 levels of them singing!" she wrote. "Amazing!"
