This is the version from the secret wars with piano. The album version may be different.

Tuning is half a step down.

I want to look at what we did
         F
So we can stand up all together
         C
Cause we put an end to it
                Am
And there'll be no more pointless fighting
         Dm
No more money running it

We'll bring back love

Now I was standing in a Chapel
        F
It's not something I normally did
          Dm        
But I was broke and a mess
       Am           G
And I had nothing to get
            C
A man put money in my pocket
           F
I just stared straight up and looked at him
             Dm
He said "Go take it son
              Am          G
You could do much more with it."
      Dm          Am             G
And we all could learn from him
         Dm        Am             G
Yeah I will never forget what he said

Now I was walking down my sidewalk
     F
I just paid my final debt
     Dm       
I see a woman and her son
             Am            G
Yeah they had no place to live
 C
The boy was turning out his pockets
             F   
I heard him wish he had a bed
           Dm                      Am              G
I said "I have some room you could use to get back in."
     Dm                   Am              G
She said "I'm not sure if I can pay you for this"
That's fine, I'm hoping...

I hope I'm standing here,
 F                     Fm
With my head held high;
                  C
My arms up in the air
