Taylor Swift Takes The Stage At Kenny Chesney’s Concert in Nashville to Sing “Big Star” [VIDEO]

It's always fun when you have another star in the audience at a big concert.  Kenny Chesney brought Taylor Swift on stage at his Nashville concert over the weekend.  She sang "Big Star," which of course is a fitting song for her.

The audio isn't great, and I think that's why they both sound off key.  It's pretty common when recording something live on your camera phone.
