Normally when a large group of high school kids take over a hotel pool, there might be cause for alarm from the hotel guests. Not in this case.

The Stillwater Minnesota Concert Choir was in Ames, Iowa for a concert and while hanging out at the hotel, many decided to go for a swim. They found the acoustics of the pool to be just right and broke into song. They performed F. Melius Christiansen's "O Day Full of Grace" beautifully and I'm guessing not one hotel patron called the front desk to complain.

So far their video has had quite the splash. It's been seen by over 1.3 million people so far. Now THAT's something to sing about!
