Roy Smith normally spends his days cleaning the hallways of Omaha’s Burke High School in Nebraska. Recently however, Smith blew the doors off the place when he took to the school’s stage for their spring orchestra concert. What followed was an incredible rendition of Sam Cooke’s “A Change Is Gonna Come.”

Not only does Smith have a rocking suit, but he’s got a rocking voice too! One that earned him a fully justified standing ovation.

This goes to show that people can be so much more than what they appear to be during work hours.
