If you watch the music video for the acoustic song, he only plays these four 
chords, so I'm pretty fang sure this is right =). The entire Acoustic song is:

F (133211@1)      C (x32010@1)       G (320003@1)      Am (x02210@1)F (133211@1)           C (x32010@1)               GUsed (320003@1)to come around here every day

Take yourself down
Pick yourself up
Everything changed when you got along
7 point 1 took it all down
Suddenly you can't even be found
I said all night long

FMissing (133211@1)person's in the window
CStaring (x32010@1)at me
G (320003@1)                  AmSaying (x02210@1)things I cant hear
          FA (133211@1)missing person's in the window
