National Anthem screwup at a Basketball Game

There was a moment of silence in honor of the people who died when the airplane crashed into a house in Philadelphia! Then a Canadian female singer sang "O Canada", the Canadian National Anthem! Then, the US Marine Corps presented the colors! Then an American female singer started to sing "The Star Spangled Banner", the American national anthem! Suddenly, the female American singer screwed up "The Star-Spangled Banner" by mixing it with "O Canada!" Everybody booed the female American singer off the stage! The female American singer never sang again! Her career was over!
