The term "anthem" always disturbs me, it have to be a song that everyone agrees with or even likes to be an anthem.I think you skipped the word doesn't, Ron, didn't you?
Anyway, I was about to post something similiar. After all, I'm not overly fond of "Oh say, can you see?", but I can't deny that it is my country's anthem, and that something happens when everybody sings it...
