CMT's Can You Duet finalists performed Thursday (July 30) at the Country Music Hall of Fame and Museum in Nashville during a luncheon hosted by the Nashville Superspeedway and Toyota Motorsports. Big Machine Records president Scott Borchetta, who is also a Can You Duet judge, introduced the three acts -- Ryan & Avalon, JB Rocket and Steel Magnolia. Prior to the performances, NASCAR Camping World Truck Series Toyota driver David Starr and NASCAR artist Sam Bass spoke to the audience where Bass later unveiled his Gibson Les Paul trophy guitar. The guitar will be awarded to the winner of the Craftsman Truck series' Toyota Tundra 200 on Saturday (Aug. 1). Bass will serve as the grand marshal, and former Tennessee Titan Frank Wycheck will drop the green flag to start the race. The Can You Duet season finale premieres Aug. 8 at 9 p.m. ET/PT on CMT.
