(NBC News) -- It's true what you're hearing about what you heard not being "true." Beyonce's spectacular inaugural performance of the national anthem was indeed lip-synched.
To be fair, all music used in the inaugural events is pre-recorded in case there is any reason -- such as extreme cold or other inclement weather conditions -- that would warrant using a track over a live performance.
"The Marine Band did perform live for the ceremony, parade, and even the prayer service today," DuBois said Tuesday. "At the very last minute, just before she went out, we received the instructions," DuBois said of Beyonce's decision not to sing live.
Publicists and agents for Beyonce did not respond to requests for comment.
