The 2017 CMA Awards got off to a huge start with a huge all-star collaboration.

Eric Church began the show, singing "Amazing Grace" a capella out of the silence. He handed off to Darius Rucker and Keith Urban, who sang a portion of "With a Little Luck," joined by Lady Antebellum, then morphed into "Hold My Hand."

The stars were joined onstage by a civilian choir, and Urban took a typically showy-but-melodic guitar solo as only he can before they landed back on the chorus to finish off the high-energy performance, with more and more stars hitting the stage as they went along, including Little Big Town, Ronnie Dunn, Tim McGraw, Thomas Rhett, Reba McEntire and more. It looked like every star set to appear on the broadcast hit the stage for the once-in-a-lifetime performance.

Co-host Carrie UnderwoodGarth Brooks and Luke Bryan are also due to perform, as well as Jon PardiMiranda Lambert,  Brothers Osborne,  Old Dominion and more.

Alan Jackson is set to make a special appearance, and the 2017 CMA Awards will also feature all-star collaborations between Niall Horan and Maren Morris, Brad Paisley and Kane Brown,  Kelsea Ballerini with Reba McEntire and Dierks Bentley with Rascal Flatts.
