Beyoncé is accused of lip-synching

Singer Beyoncé has been accused of lip-synching her performance of the American national anthem at Barack Obama's inauguration.

The United States Marine Corps band initially confirmed that the singer lip-synched her impressive rendition of The Star-Spangled Banner.

The news, revealed by The Times and confirmed by ABC News, was also confirmed by a spokesperson for the band on their Washington blog:"We don't know why Beyoncé decided to use pre-recorded music.

"All music (for inaugural ceremonies) is prerecorded as a matter of course, and that's something we've done for years and years."

According to The Guardian, they added: "The band played live for the rest of the ceremony, but was asked to use the pre-recorded track for Beyoncé's performance."

However, later, Captain Gregory Wolf, a spokesman for the Marine Corps, confirmed that while the musicians did indeed mime the national anthem as requested, "no-one in the Marine Band is in a position to assess whether it was live or prerecorded".
