(KUSA) - Every Denver Broncos fan knows that quarterback Peyton Manning has a great sense of humor.

He showed not only his humor, but his vocal cords off on Saturday at his seventh annual Celebration of Caring Gala.

Manning stole the show when country star Jake Owen invited him on stage to sing "Folsom Prison Blues."

More than $1 million was raised for the kids at Peyton Manning Children's Hospital at St.Vincent in Indianapolis.
