Rascal Flatts did a little Las Vegas rehearsal in Los Angeles Wednesday night. The country trio, set to begin their residence at Sin City’s Hard Rock Hotel and Casino next week, brought two songs sure to be on their Vegas set-list to Jimmy Kimmel Live . Lead singer Gary LeVox’s voice soared on the group’s new single, “Riot,” on ABC’s late-night talk show. He joked that helium is on the Flatts’ concert rider so that he can hit all those high notes on the song.
