Yeah, she made TWO major errors in the lyrics.
"Oh say does OUR Star Spangled Banner yet wave?" WRONG!!! It's "THAT Star Spangled Banner."
Oh, for her second error, she sang "And the home of OUR brave" instead of "And the home of THE brave"...
However, I won't comment on the quality of her singing, only because my singing voice has been declared a war crime under the Geneve Conventions...
That is the extent of her mistakes?
If that is the case, you and everyone who is making a case out of this are fools.
She'll claim she's trying to be "inclusive" (our for that and our for the.)
