Did Beyonce lip sync the national anthem at yesterday’s Inauguration (reminiscent of 2009)?

It certainly looks that way, as the Times of London is claiming that despite her energetic performance, Bey was “lip-syncing to a pre-recorded backing track.” For evidence, the Times quotes a spokesman for the Marine Corps Band, who told says that it's “standard procedure to record a backing track, and Beyonce decided shortly before her performance to rely on the studio version rather than risk singing it live on the Capitol.”

If Beyonce did lip synch, it wouldn’t be the first time. Back in 2009 she came under criticism for allegedly lip syncing her Broadway tribute at the Oscars.

Can you determine if Bey lip synced SSB?

Does it really matter?
