Pop star Beyoncé sang a rendition of the National Anthem during inaugural ceremonies in Washington Monday, a spokeswoman for the U.S. Marine Band tells CNN. Beyoncé "pre-recorded" the song the evening before Inauguration Day, after rehearsing with the U.S. Marine Band. According to the band's spokeswoman, such pre-recordings are "not unusual." Many inauguration viewers may have also noticed Beyoncé pulled her ear piece out during her performance. But DuBois did not have an explanation as to why the pop star removed the ear piece.
