These are the exact chords played in the song,
but I like the whole G, Cadd9 type of sound to acoustic songs. 
So I redid the chords a little to my liking. 
And since this song is in the key of "G" these chords sound really nice. 
Hope you like it (:
Also, one little note on the chorus. 
In the real song when he plays the "G" and then the octave, 
I sortof do the same thing on the acoustic. 
I'll play the G chord, and then when the octave is played 
in the song I just strum the top two strings 
to get that octave type sound. Hope this helps.
"G"  "Em"  "Cadd9"  "D"
