On Wednesday, Taylor Swift swept through Austin, Texas on her Speak Now Tour, and per usual, she brought a few surprises. The 21-year-old 'The Story of Us' singer dished out a cover song, 'Hold On,' from local artist Jack Ingram -- and also invited a Grammy winner to the stage to play with her.

Swift dazzled the crowd with a sea of her own hits and a sparkling stage production before hitting a small round stage at the back of the arena to try her hand at Ingram's 2007 duet with Sheryl Crow. Though the singer wasn't in attendance, Swift made sure to insist that he is one of the nicest artists she's ever met and that he has treated her kindly since day one.

Later in the show, the 'Love Story' songstress invited a special guest to perform onstage with her. When the fog cleared, 1998 Record of the Year winner Shawn Colvin appeared next to Swift, and together, the pair sang the award-winning track that made Colvin famous -- 'Sunny Came Home.'

Taylor Swift's Speak Now Tour picks up again on Oct. 29 in Lexington, Ky.
