According to Billboard:
A Marine Band spokesperson explained to CNN and Washingtonian.com on Tuesday that all music for inaugural ceremonies is recorded as a precaution. “That’s something we’ve done for years and years. The Marine Band did perform live throughout the ceremony but we received last-minute word that Beyoncé wanted to use the recording.”
Band director Colonel Michael J. Colburn told BuzzFeed Shift that Beyoncé didn’t rehearse with the United States Marine Band till the night before the inauguration. “We had Kelly [Clarkson] in over the weekend to rehearse and record. Beyonce, she’s getting ready for the Super Bowl, so we didn’t have a chance to do anything with her until last night so it’s a very, very tight window of opportunity,” he said.
Don’t big celebrities do this all the time? Also when she took out her ear piece during the performance… what was that about? Anyhoot Beyonce looked and sounded great!
UPDATE: 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.
