Theme Song for the Saints
I was just talking about something similar to a coworker of mine. When the Bears won, they had an actual fight song that the entire crowd was singing. I know very few NFL teams have a "Fight Song", but the ones that do sound really cool when they sing it. The Houston Oilers had a great one back in the day.
Someone more talented than I should come up with a very simple fight song to sing when we win a game that is simple enough to remember when everyone is fall-down drunk.
