Rachel Platten Messes Up Singing The National Anthem

RACHAL PLATTEN of "Fight Song" fame has joined the exclusive club of artists who've made a travesty of the national anthem.  Luckily, it happened at a soccer game, so nobody saw it.  I'm kidding . . . it's all over the Internet.

Rachel re-started the song TWICE, because she kept saying, "By the STARS' early light."  After the second time, she said, "Someone tell me the next line."  She said "stars'" again the third time, but she kept going and finished strong.

Rachel told "People" that she CRIED after it was over . . . adding, quote, "It was like a test that you know all the material to, you study so much and you get in there, and your mind doesn't cooperate."
