While replacing "at the twilight's last gleaming" with " were so gallantly streaming," might seem like a simple enough mistake to make in front of a large crowd - it was actually Lewis himself who lambasted Christina Aguilera back in 2011 for her screw up.
"I guess I just don't understand how people who sing The National Anthem can be so f—ing self-absorbed that they would try to change that f—ing song. If there is a single song in the history of this country that deserves no creative interpretation, it's that one."
All I can say is I'm sorry and ask for the Nation's forgiveness. My nerves got the best of me and I am completely torn up about what happened. America is the greatest country in the world. The Star-Spangled Banner means so much to so many, including myself. I hope everyone can understand the intensity of the situation and my true intent of this performance. I hope that the Nation, Major League Baseball and the many fans of our national pastime can forgive me.
