This is pretty much as complicated as the song gets.
Occasioanally it stops on A—7 for a moment.

G|————————————————————————————————————|
D|——————————14~——————————14——13———————|
A|————————————————12———15——14—————————|
E|——12~———15——————————————————————————|

You can play it starting on the seventh fret on A
as well or even an octave down with open strings
but I think this method provides the fullest sound.

Have fun.
