Tim McGraw and Faith Hill certainly know how to open a show! To kick off a recent concert in Charleston, S.C., on their 2017 Soul2Soul Tour, the country couple delivered a duet from two of music's other biggest superstars: Aretha Franklin and George Michael.

"I Knew You Were Waiting (For Me)" is a perfect fit for the country singers, who do the legendary duo justice with their strong harmonies and enthusiastic delivery. Hill, dressed in a sheer, glittering dress, and McGraw, who looks sharp as always in an all-black outfit and his signature cowboy hat, demonstrate their unique passion throughout the performance, which concluded with thunderous applause from the crowd.

Recorded by Franklin and Michael in 1987, "I Knew You Were Waiting (For Me)" was one of the biggest hits in Franklin's catalogue, topping Billboard's Hot 100 chart after its release. The song also earned the two singers a Grammy in 1987 for Best R&B Performance by a Duo or Group With Vocal.

The crowd in Charleston got quite a treat that night, as McGraw and Hill also debuted a fiery new song titled "Break First", which is set to appear on their first ever duets album when it comes out later this year. The first single, "Speak to a Girl," is currently impacting country radio.

The power couple's 2017 Soul2Soul Tour launched on April 7 in New Orleans and keeps the dynamic duo out on the road most of year before wrapping up on Oct. 27 in Brooklyn, N.Y. Just some of the country stars set to hit the road with McGraw and Hill: Jon PardiCam, Brandy Clark and Chris Janson.
