There's no question Beyonce's rendition of the national anthem was a roaring success. The mystery: was it live or lip synced?
On Tuesday, a spokeswoman for the U.S. Marine Band told news outlets that Beyonce had lip synced at President Barack Obama's inauguration. Master Sgt. Kristin duBois said the band was notified at the last minute that Beyonce would use a pre-recorded voice track.
But by late afternoon, the Marine Corps backed off that statement.
Marine Corps spokesman Capt. Gregory Wolf said that because there was no opportunity for Beyonce to rehearse with the Marine Band, it was determined that a live performance by the band was ill advised. Instead they used a pre-recorded track for the band's portion of the song.
"Regarding Ms. Knowles-Carter's vocal performance," Wolf's statement continued, "no one in the Marine Band is in a position to assess whether it was live or pre-recorded."
A representative for Beyonce did not respond to requests for comment.
DuBois declined to answer further questions. Earlier in the day, she told The New York Times that the rest of the inaugural performance was live and they did not know why a recorded track was used for the national anthem.
"It's not because Beyonce can't sing. We all know Beyonce can sing. We all know the Marine Band can play," she said.
