How do they pick who sings it, and why is it always a celebrity. Do you think that if somebody sent in a tape of them singing, they could sing the national anthem at the superbowl?
its possible but highly unlikely. They pick celeberties to sing the national anthem and play at halftime because it not only puts more people in the stadium but it also increases the home viewing audience number as well
Given the scope of the event and going worldwide, you'd definitely want a seasoned professional to sing it - at a lesser event a novice might be used but not in that environment...Merry Christmas !!
