Avicii - Hey Brother chords

This is my first tab, any improvements appreciated! :)
(And it's not the right key, I know, this is just easier I think)

Am                      F       C       G     Am
Hey Brother, there's an endless road to re-discover.
Am                 F       C         G        Am
Hey sister, no the water's sweet but blood is thicker.
G                 C         F       G    
Oooh with the the sky comes falling down, for you,
        F               G                Am
there's nothing in this world I wouldn't do.
