Romance is usually in the air during fair week but this year’s fair romance meter was off the charts. Becky Medlen, the daughter of Warren County A&L acting president Kenneth Medlen, got the surprise of her life Friday night when she was called onstage by singer Cody McCarver.McCarver seated Medlen on a stool while Adam Dean Mullins serenaded her with what the audience was told was her favorite song, “Wagon Wheel.” A little over halfway through the song, Medlen’s boyfriend of two years, Joey Clark, unbeknownst to her, was making her way across the back of the stage.
