Glasvegas - Go Square Go chords

Ok, this is the first ever song I've attempted to transcribe, due to the fact I 
couldn't find a tab of it anywhere.  It's probably wrong, but I'd appreciate your 
feedback.  Thanks.
[ Tab from: http://www.guitaretab.com/g/glasvegas/185031.html ]
G                     C
If he wants to fight you
                G     C
At the school gates
G                        C
Half past four grab your bag
              G      C
Don't you be late
G                    
If he wants to hit you
C
Hit you in the face
G
If he wants to hurt you
C
In front of your mates
G               C
If he wants you to run away
     G
Run away run away
          C
Don't you fucking run away
G    D     C   G
Go square gooooooo!

Don't you wait for the bell
To ring ding-a-ling-a-ling
One step forward then a
Bada-bada-bing
Don't you make me

Go down to the pub
With all my mates knowing
Some individual smashed you up 
It's just something
That you'll have to face
Face to face
Man to man
Here and now
Biff bang pow

Go square go!

I don't really feel to good
My heart is beating faster
My dad told me
Not to come home
If I don't kill this bastard
My dad is right, my dad is right
My dad is right, my dad is right
Win, lose or draw the fight
If I don't fight, I can't go home tonight.
