Trisha Yearwood performed the Star-Spangled Banner to kick off game 1 of the World Series today and totally knocked it out of the ballpark. Seriously, this is how it's done. Amazing.

Little Big Town will also be performing the national anthem this week during the World Series on Friday in San Francisco before game 3.
