Rascal Flatts surprised two married fans who were renewing their wedding vows in Indianapolis on Saturday night (July 23). The Flatts Fest tour is traveling with the "Why Wait" wedding chapel, and the group made an unannounced appearance inside as Anthony Payne and Stephani Giveans were renewing their vows. Radio personalities from local country station WFMS presided over the ceremony. After that, Rascal Flatts took the stage on the tour's traveling Karaoke Challenge, locally hosted by country station WLHK. After cheering for contestant Jessi Bennett, the group sang a shortened karaoke version of "Bless the Broken Road." Rascal Flatts' next tour date will be Friday (July 28) in Atlanta.
