Did Beyonce lip-sync?

Did she, or didn't she? Claims that pop singer Beyonce lip-synced during her performance of the Star Spangled Banner at President Obama's inauguration have U.S. media abuzz.

A spokeswoman for the U.S. Marine band told one media outlet the singer opted for pre-recorded music at the last minute.

But Beyonce's team has not commented on the issue.

Later, the U.S. Marine band backtracked saying quote, 'no one in the U.S. Marine Band is in a position to assess whether it was live or pre-recorded.'

For fans, it didn't seem to matter.

(SOUNDBITE) (English) ROSE WASHINGTON, FROM LONGWOOD, FLORIDA, SAYING:

"Lip-synch or not. I don't think you can lip-synch the notes she hit yesterday. So, and it was wonderful. It was wonderful. It's not a big deal to me."

(SOUNDBITE) (English) TORREY VELOZ, FROM GLENDALE, CALIFORNIA, SAYING:

"I know she can sing so I don't think it was bad that she was lip-synching. Maybe it's just because they don't want to mess it up, because of the inauguration."

Previous inaugural performances- Yo-Yo Ma in 2009 for example- were pre-recorded because the cold and wind might have caused sharp notes.
