Keith Urban's Raise 'Em Up Tour came to Denver recently, and the 'Somewhere in My Car' singer showed why he's one of the most exciting live acts in country music. Urban, Brett Eldredge and Jerrod Niemann played Fiddler's Green Amphitheatre on Aug. 29, but it was a surprise guest that left everyone talking.

Lindsay Taylor from nearby Lyons, Colo. won a contest to sing Miranda Lambert's part on Urban's 'We Were Us.' Urban runs a similar contest at many of his tour stops. Taylor's sister caught the entire performance on her iPhone, and the newbie more than held her own alongside the country legend.

Eldredge and Niemann also came out on fire, giving the packed arena something to cheer for from start to finish. See exclusive photos of the show below!
