The musicians hit the stage in Nashville, Tennessee on Monday (31Aug15) to perform for American Saturday Night: Live From the Grand Ole Opry.

Shelton performed his hits Hillbilly Bone, Sangria, Gonna, Boys 'Round Here and Ol' Red, while Paisley sang Southern Comfort Zone and paid tribute to his late pal Little Jimmy DICkens, who died in January (15).

He told the crowd, "The thing about being a country singer is that there are sort of two places you play. There's the Grand Ole Opry... and everywhere else."

The film about the life of the country music mecca will hit theatres in December (15).
