Intro/Verse chords:

Dm, Am, Dm, Am, Dm, Am, E7, and then this sequence ends on this chord:

"E4/7(11)"
e|--x----|
B|--10---|
G|--7----|
D|--7----|
A|--7----|
E|--x----|

However, note that this whole song is fingerpicked, so that only certain notes of each 
is emphasized. In the E7 chord, the guitarist actually does a little slide up from the Am 
then fingerpicks the E7 so that it looks like this:

e|------------------|
B|--------9-10~-----|
G|--------7---------|
D|------9---7~~-----|
A|--5/7-----7~~-----|
E|------------------|
  ---E7---- E4/7(11-|

So there you go. There are little variations for the E7 to E4/7(11) ending in the verse, 
I'm not gonna tab that crap out.

For the chorus, it's pretty simple:

Dm, Am, E, Am, Dm, Am, E

... and that's it. Keep in mind that these chords are played up on the neck, not in open 
For example, the E chords here are not played as

e|-0-|
G|-0-|
B|-1-|
D|-2-|
A|-2-|
E|-0-|

but as

e|-x-|
G|-9-|
B|-9-|
D|-9-|
A|-7-|
E|-x-|
