High School Janitor Wows With Sam Cooke Classic At Orchestra Recital

It's been a long, a long time comin'.

A janitor who cleans Omaha Burke High School in Nebraska blew the doors off the place last week when he gave a killer performance during an orchestra recital.

Video of Roy Smith belting out the 1964 Sam Cooke hit "A Change Is Gonna Come" has since gone viral. Wearing a bright pink suit, he hit all the right notes in all the right places.

According to Inside Edition, Smith has been singing since he was 13 years old. He was offered a recording deal in his early 20s, but turned it down because he thought it was too risky. Nowadays, he mainly sings with gospel groups.

Last Tuesday's performance may be the first time his talent was revealed to a wider audience. Smith, who's originally from New Orleans, said he's more known for singing while going about his job.

"Whistle while you work, that's my motto," he told ABC News. "I'm like that every day. It brings joy to the students. The ones that are down and out, I give them something to cheer them up."
