Taylor Swift brought her Reputation Stadium Tour to Nashville, the place she says taught her everything she knows about being a musician, Saturday night (Aug. 25). Nashville proved to be the perfect setting for an incredible surprise: country greats Tim McGraw and Faith Hill both joined Swift onstage for an unforgettable performance of her debut single "Tim McGraw."
"When you think Tim McGraw," she sang, while casually pointing at Tim McGraw to her left, "I hope you think my favorite song."
"Every single thing that I do I've learned in Nashville, and I'm so incredibly grateful," the "Delicate" singer had said mid-show at Nissan Stadium. Before her surprise guests appeared on stage with her, she performed country ballad "Better Man" -- the award-winning song she wrote, but Little Big Town recorded -- acoustic on the B-stage.
