Poor Rachel! The "Fight Song" artist had a tough go at the National Anthem.
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."
