E                           A

E                           A

                        EEE
(I Think its time we) stop Children
DDD
Whats that sound 
AAA
everybody look 
CCC
whats going down

then its the same till the verse that says 

E                       E  A  G 
What a feild day for the heat

                    and that verse is like that


for the chorus, using power chords is also cool, if you're aiming 
for that sound...but otherwise it doesn't really matter.
