Before playing their debut single, “Later On,” the former season 4 The Voice stars kicked off their performance by singing a bit of George Jones's "Who's Gonna Fill Their Shoes." Midway into the song, however, the moment quickly became about their parents, whom the brothers called to the Opry stage in appreciation, noting their sacrifices to help the Oklahoma singers achieve their musical dreams.
"Playing the Opry for the first time is something one can't describe," Colton Swon told PEOPLE Country after the show. "Dreaming all these years of singing on that stage did not even come close to the real-life moment."
His brother noted that they were in awe of the Opry's fabled place in country music as they stepped before the nearly full Nashville hall. "So much history and greatness surrounded us," said Zach Swon. "It's every country singer's dream to stand on that stage. What a life-changing experience that I'll never forget."
By the time the duo, who were signed by Arista Nashville after coming in third on The Voice, got around to playing their own songs, the audience was cheering and tears were flowing all around.
Later, the brothers posed for photos with Opry legends Little Jimmy Dickens and Jeannie Seely. Once backstage, they welcomed fans, including one teen who had skipped out on her senior prom just to make sure she got to see boys in their Opry debut.
