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!"
