Intro 
In the intro and chorus, this is the basic idea of the riff.
I believe he sometimes just goes back to A at the end of it,
really fast, instead of using these slide motions.

G-7----------------
D-7--7--/9-/7/9/7--
A-5--7--/9-/7/9/7--
E----5--/7-/5/7/5--
Play this a few times, then on the last time play:
G-7-----------
D-7--7--8-----
A-5--7--8-----
E----5--6-----

Verse
I'm pretty sure it's just D and G over and over.

G-7-------
D-7---5---
A-5---5---
E-----3---



I don't know what instrument plays during this break,
but I think it starts with some kind of E chord.

Chorus

G-7----------------
D-7--7--/9-/7/9/7--
A-5--7--/9-/7/9/7--
E----5--/7-/5/7/5--
PLay above riff 3x, then play
G-7-----------
D-7--7--8-----
A-5--7--8-----
E----5--6-----

Bridge- 

G---------------------------------
D-8---10--12--10--8---10--12--7---
A-8---10--12--10--8---10--12--7---
E-6---8---10--8---6---8---10--5---
I believe this bridge to be mostly correct, I'm just can't seem
to figure out what one of the chords is.
