Why?
Official Chess Anthem?

I think this would be a fun anthem... not that it has anything to do with chess...
I'm technologically challenged, so 5 bucks says the above embedding doesn't work :S
EDIT: Of course it doesn't...

I think this is chess related but I don't know if it should be a theme song lol!

Bobby Fischer beat Spassky in Iceland '72,
I know a girl who's better looking but who thinks like Bobby Fischer too,
When Bobby Fischer was a kid they knew he was a prodigy,
I know a girl who's somewhat older but no less of an authority.
I wish I had the smarts to understand her charts,
If I don't concentrate she'll have me in checkmate.
In Tampa Bay and Lafayette they all knew Bobby Fischer's name,
I know a girl who made her mark in smaller cities but her fame's the same,
When Bobby Fischer made his comeback in the 90's he was worse for wear,
I know a girl who made a comeback but her mind was altogether there.
She said, "I drink chocolate milk from a cow I built,
Doot n'doot doot doot. Doot'n doot doot doot."
They're all saying that you'll never play again,
They're all saying that you're finished, that you're washed up as a friend,
All my life I have 'feather-dustered' but it's not how it's going to end,
Oh no.
Spies in hideouts send their secret messages,
There's a thief caught in the headlights of a car beneath a bridge,
There's no lights on in the house except the light in the fridge,
Oh yeah.
Reykjavik, no one ever says Reykjavik in a song,
Reykjavik, no one ever says Reykjavik in a song.

Ok, you said "not from the musical "Chess"", but hey.
One Knight In Bangkok :p
Although I'm not actually sure that's my favourite song in "Chess". But it's certainly a very good candidate.
Of course, in the category of things outside of "Chess", "Killer Queen" may be a half-decent candidate, alongside other silly ones like "Play the game" (appropriately, also by Queen), and "Dry your eyes, mate" by... whoever it was, if you want to go down the real "pun is mightier than the sword" line. Of course, we all know really that the pin is mightier than the sword, but the fork is mightier than the pin.
But as for "Chess", there are so many good songs in there that it's hard to choose.

It HAS to be this.

It HAS to be this.
Ha! The Dance of the Knights. Yes, appropriate, and very cool music!

Okay folks. With all the talent on this website; let's try & come up with an original anthem.
I'll take a stab a stanza.
On squares of 64
Our pawns march on, ever to the fore
Though our Kings abide on opposite sides
The riddle is in the middle
That leads to shame or fame
Oh Game of games!
Okay, you can kick me to the curb now. I encourage any poets or artists here to add their input. But "Game of games" sounds like a nice title.
Is there an official song for chess? or a chess organization with an official anthem? Not like music from the band Chess, or the musical Chess but a sort of official chess song. Kind of a random question.
