Alva, Lexington, Edmond Memorial, Edmond Santa Fe, Durant and Bethany are among the headlining programs in attendance.

A group from Kansas shook out as the winner of the FAME finals, a North Carolina group pulled an upset for their first win, and an Oklahoma group stayed chalk to end the season.

A national championship, a state championship, and a rare Oklahoma contest are on tap for the final big show choir weekend of the season.
