Chord progression for the entire song:

Em         C                G        D
Don't dismiss it like it's easy. 

Little lick at the beginning:

E |---------------------|
B |---------------------|
G |-----4-5-4-----------|
D |-5-7-------7-5--5----|
A |------------------7/5|
E |---------------------|

That's it! For real! Great song.
