The Capitol Street Party 3 jammed Music Row in Nashville on Wednesday (Oct. 13) with performances by the announced lineup of Jennette McCurdy, Troy Olsen, Walker Hayes, Luke Bryan and Darius Rucker.
But a special guest was also thrown into the mix, much to the delight of the massive crowd. Keith Urban bounded to the stage to join Darius on Keith's hit "Raining on Sunday" and also performed a cover of the Steve Miller Band classic, "The Joker."
Jennette, the star of the popular Nickelodeon TV series iCarly, opened the show and also did an autograph session after her performance as a line of kids and families stretched halfway down Music Row’s Demonbreun Street. The Capitol Street Party, hosted by Capitol Records Nashville, was free and open to the public.
