Hundreds of Students Sing the National Anthem in a Hotel Lobby

A video has gone viral of some 650 choir students in Louisville, Kentucky singing the "Star-Spangled Banner" off of balconies in the middle of a hotel.  Because they're in an atrium, the acoustics make it sound even more amazing.

The students are part of Kentucky's All-State Choir and they're all staying in the same hotel.  The "hallway singing" is a yearly tradition, but we're pretty sure they've never gotten this kind of exposure.
