Surprisingly, the biggest controversy stemming from President Obama's inauguration Monday has nothing to do with his birth certificate. It's whether or not Beyonce lip-synced the national anthem.

Beyoncé's performance was pretty stellar, and got rave reviews on the World Wide Web of Uninformed Opinions. But is that because she didn't actually sing it?  It's standard procedure with a performance like this for musicians to record a backing track that they can sing and play along to.

And yesterday, a spokeswoman for the Marine Corps Band, which backed up the performance, said that Beyoncé made the decision to rely entirely on that track.  She said, quote, "We all know Beyoncé can sing. We all know the Marine Corps Band can play. We do not know why she decided to go with the pre-recorded music at the last minute."

She added that the band played live for the other performers, like Kelly Clarkson, but was specifically told to fake for Beyoncé.

However, a Marine Corps spokesman later watered down that claim. But he didn't specifically deny it. He admitted that the band used a prerecorded track, because there wasn't time to properly rehearse.  But he added, quote, "Regarding Ms. Knowles-Carter's vocal performance, no one in the Marine Band is in a position to assess whether it was live or pre-recorded."  In other words, he's not saying Beyoncé didn't fake it, he's saying he doesn't know, and neither does the woman who made the initial claim.

People are also trying to make hay out of the fact that Beyoncé posted a picture of herself on Instagram, in which she's in a recording studio, holding sheet music for the national anthem.  But that proves nothing, since we already know that she did record a backing track.
