Tracy Lawrence took the stage at the 2015 Taste of Country Festival in the afternoon heat and got the crowd involved in a loud singalong, but it was when headliner Tim McGraw joined his buddy for "Find Out Who Your Friends Are" that the 20,000 fired-up country fans really went crazy.

Despite the temps on Hunter Mountain, Lawrence sported a black T-shirt and black cowboy hat. "Y'all ready to get rowdy?" he asked after his first song. He already knew the answer as he and his five-piece band — playing in front of a street sign that read 'Tracy Lawrence Avenue' — led into songs like "Better Man, Better Off" and "If the World Had a Front Porch." Then, Lawrence delivered one of his "personal favorites," "I See It Now," as the crowd grew louder. "Texas Tornado" and "How a Cowgirl Says Goodbye" followed soon after. The hitmaker mentioned how he's been pursuing his country career for well over two decades, and it was obvious he's made an impact — the crowd knew all the words.

"Sticks and Stones," one of his most recognizable songs, was next. A beach ball flew through the air, and Lawrence didn't miss a beat as he kicked it off the stage, saying: "What a great crowd you guys are!"

"Alibis," "Time Marches On" and "Paint Me a Birmingham" also made the 16-song set. And then ... "Find Out Who Your Friends Are." Lawrence was well into the song when a familiar face — McGraw — appeared onstage in workout clothes to support his friend, whom he says is "one of the best country singers in the world."
