Saturday night's finale for the Battle for the Big O is already a star-studded line-up. That night, eight phenomenal tri-state music acts will fight for the chance to win $500 and open for Blake Shelton at the 2012 Big O Music Festival at Reid's Orchard in Owensboro. And now, WBKR is pleased to announce a very special guest performer who will be keeping the audience entertained while our judges deliberate and choose the winner. Yep! She's 9-year-old Skylar Cain, who recently performed at the CMA Music Festival in Nashville. On Saturday night, she'll be performing for us. Here's a sneak peak!
