C5 E5 F5                 G5       C5 E5
Play something that we need to hear
F5                G5        C5 E5
Play to make the ghosts appear
F5          G5           C5 E5 F5 G5
Play until the bottles gone

That chord sequence is then repeated through the song, until:

E5             A5
Play it in the streets, Play it in the schools
F5               F5                      G5              G5           C5 E5 F5 G5 
Play it for the ones out there who?ve never seen what playing can do

Then it returns to the main chord sequence until the end of the song.

Pretty simple, but a great song.
