This song is ridiculously easy so I'm not going to go through the whole song and place 
specifically where each and every chord change is. The song is a step up so if you want 
to play with the recording put a capo on the 2nd fret.
The chord progression is C G AM F. And it just repeats.

C        G        Am      F
