Ronnie Dunn fans are concerned for the country singer after he abruptly walked off stage during his Thursday night concert in Indianapolis. The 71-year-old Brooks and Dunn member was singing “Boot Scootin’ Boogie” during the show’s encore when he gestured to another band member that he was done performing. In a TikTok video, he pounded his heart and waved to the audience before walking off stage. Representatives for Brooks and Dunn haven’t commented on his exit.
