Dillon Carmichael was once a security guard at the Grand Ole Opry. On Tues., Aug. 21, the 24-year-old, Burgin, KY native made his Grand Ole Opry debut. Though he was allowed to step into the circle while working security, he never did. He purposely saved that moment for last night, and it was a night that earned him two standing ovations over the course of three songs — welcomed by an introduction to the stage from his uncle Eddie Montgomery of Montgomery Gentry.
