Performing the national anthem at the Super Bowl or any sporting event is always a nerve-wracking task, since pop stars tend to flub the lines with regularity. Maybe it's nerves. Maybe it's the pressure and being on such a national stage. Who knows. But it happens... a lot. Alicia Keys performed 'The Star-Spangled Banner' at Super Bowl XLVII tonight (Feb. 3), seated at a white piano in the middle of the field. We're proud to report that it was flawless, both lyrically and melodically.
