The chords are simply played in a strum bass,2,1 and you can enter some 3 and 4 between 
to "fill it up"
In the G I prefer open e string and D not playing it at all..
I added a special intro that is very close to the original piano.
It's just recommend, if you feel it's too hard try the alternative.
The whole point is to play with the e string, use the strum, it will help.

G* =  320030
Am5 = x02211
D* =  xx023x
E* =  022111

Intro: |Am|E|G*|D*|Am,Am5|E,E*|G*|D*|

(or Alternative Intro) :
|Am|E|G|D| x2
