If it's sport, I love this anthem (YouTube) from Australia about a legendary Aussie rules footballer :

Up there Cazaly,
In there and fight
Out there and at 'em
Show 'em your might.
Up there Cazaly,
Don't let them in.
Fly like an angel,
You're out there to win.

Up there Cazaly,
You're out there to win
In there and at 'em,
Don't let them in.
Up there Cazaly,
Shown them you're high,
Fight like the devil,
The crowds on your side.
