Did Beyonce' lip-sync the national anthem at the inauguration, or didn't she?

A spokeswoman for the Marine Band initially said Beyonce' did, but now the U.S. Marine Corps says no one in the band is in a position to say for sure.

A Marine Corps spokesman says there was no opportunity for Beyonce' to rehearse with the Marine Band. He confirms the band did not perform live. All the music for the inauguration was recorded in advance in case of a problem.

Kelly Clarkson's representative says Clarkson sang live for "My Country 'Tis Of Thee."

Beyonce's representative has not responded to requests for comment.
