Sara Evans, Warren Brothers Find Pulses Calm at ACM Rehearsals

Neither Sara Evans nor the Warren Brothers — Brad and Brett — can be considered veterans of network TV, but they don’t have jitters about their performance together Wednesday (May 9) on CBS. With three award nominations between them, Evans and the Warrens have earned the right to strut their stuff in front of a national audience. On a set complete with disco ball, they will perform “That’s the Beat of a Heart” near the end of the 36th Annual ACM Awards at the Universal Amphitheatre.
