Carrie performs on 'Saturday Night Live'

Carrie Underwood was the musical guest on the first episode of Saturday Night Live since the writer's strike ended. The episode was hosted by SNL alum Tina Fey and Carrie performed her latest single "All-American Girl" in addition to "Flat On the Floor."

Her vocals were noticeably lackluster on "Girl" and there seemed to be a problem with the balance between the volumes of the microphone and the band, but she managed to deliver a show-stopper with "Floor." Watch the performances below and make your own decision.
