This is the acoustic part in the middle and end of the song. I just play them as power chords. Keep your right hand strumming constantly throughout, scuffing the strings in between the chord changes.
G F C Bb F C F (play twice)
hi-ding backwards in-side of me i feel so unafraid

I felt sorry for the people out there who don't know much about chords so I TABed it for you.
