Sloshed Anthems

One more question inspired by watching the World Cup: Is there a national anthem that, when sung by the soccer players and fans of that country, doesn’t create the impression that everyone is drunk?

Seriously. If you didn’t know any better and turned on the TV and listened to the players and fans sing the national anthem, you would swear they had each drunk a bottle of vodka and chased it with a Colt 45.
