They are not using perfectly, exactly the same chord arrangements everywhere
as I described, but mostly I tried to copy the same.
I am using intentionally my own F/G and G/A combination at the
"I'm breaking out" lines, but that is just because I like that sound more.
In real it is simple F and G.

Sorry for the invented chord names, I'm too lazy to look for their real names.

      And I'll be fine if you go and take a piece of my soul.
             C              C/A   
      That's when I've been thinking
          F/G             G/A
