The band didn't really play, either. The Washingtonian's Sophie Gilbert had this assertion:

To press seated just below the podium, in front of the “President’s Own” Marine Corps Band, it was evident that the band wasn’t actually playing during the song—even though band director Colonel Michael J. Colburn was conducting energetically and the band members mimicked blowing into their instruments. Separately, at one point during her performance, Beyoncé removed her earpiece.

I care nothing about what shouldn´t have taken place yesterday.

Why is anyone surprised that this Administration and all it´s supporters are more interested in appearance than substance, spin rather than the truth? They cheat at everything to gain advantage-even singing the National Anthem. I am sad that the Marine Band was complicit in faking it as well. Nice role model for your daughters BAM. Lies, lies lies. About everything-even our Anthem.

This is because the woman can´t sing. Electronic assistance is needed not only to make her "talent" somewhat bearable to the human ear, but also to avoid calling in dogs from miles around.

Simulated performance by all.
