Carrie Underwood brought the Christmas spirit to Rolling Hills Community Church in Franklin, Tenn. with a surprise performance during their Christmas Concert. Attendees had no idea that Carrie was going to sing. Videos show her singing "O Holy Night" and "Have Yourself a Merry Little Christmas." Carrie actually performed at that church in August with a surprise rendition of "Goodness of God" alongside the church's worship team and choir.
