The pressure of the moment, the crowd, the lights, it can all be overwhelming for anyone but it didn't help that the house announcer read off a long list of accomplishments for Lady Antebellum before Charles had a moment where he couldn't remember the next line in the Star Spangled Banner.
But then, as Hillary took a breath before the next line, Charles went full steam ahead and jumped to the lyric 'were so gallantly streaming'.
As Hillary began to sing the correct line - 'O'er the ramparts we watched' - looked like Charles knew it right away. The players couldn't be seen reacting and some laughs could also be heard in the crowd.
These words should be memorizes by Every American.
O say can you see, by the dawn's early light,
What so proudly we hailed at the twilight's last gleaming,
Whose broad stripes and bright stars through the perilous fight,
O'er the ramparts we watched, were so gallantly streaming?
And the rockets' red glare, the bombs bursting in air,
Gave proof through the night that our flag was still there;
O say does that star-spangled banner yet wave
O'er the land of the free and the home of the brave?
