Yesterday, in charge of singing the National Anthem of the United States at the ceremony of the Super Bowl, that is, Christina Aguilera was wrong to sing the verses, so you had to ask for apologies to the public.The error was Christina was as follows: Instead of singing "O'er the ramparts we watched, Were so gallantly streaming" ("We watched from the trenches who was flying so gracefully"), the singer repeated the above line with a slight change, ie, sang "What so proudly we watched at the twilight's last gleaming"
