I've been absolutely crazy about this song and decided I'd go ahead and tab it out since
a few people seemed eager to learn it based on the youtube comments. I'm basing it
mostly off of the acoustic video they have up, in the recordings he plays the same
chords but not necessarily in the same order. Any input/corrections are welcome!

Standard Tuning:

E|--------0--------0--------0--------0-|
B|------0--------0--------0--------0---|
G|----9--------9--------9--------9-----|
D|-11-------11-------11-------11-------|
A|-------------------------------------|
E|-------------------------------------|


E|---0-------0-------0-------0-------0-------0-------0-------0-------|
B|-----7-------7-------7-------7-------9-------9-------9-------9-----|
G|-------6-------6-------6-------6-------8-------8-------8-------8---|
D|-7-------7-------7-------7-------9-------9-------9-------9---------|
A|-------------------------------------------------------------------|
E|-------------------------------------------------------------------|
                                                   *       *

----0---------0---------0---------0--------------------------------------|
------12--------12--------12--------12-----0-------0-------0-------0-----|
---------9---------9---------9---------9-----9-------9-------9-------9---|
-11--------11--------11--------11--------------8-------8-------8-------8-|
-----------------------------------------7-------7-------7-------7-------|
-------------------------------------------------------------------------|x4

*During the 2nd and 4th repeats, he plays something slightly different on the D string,
it should read D|--7---7---7---7---9---9---10---10---; The rest of the strings stay the same


The strumming during the next section is easy to figure out.

E|----------------------12--4---|
B|--7--9--12--5---7--9--12--2---|
G|--6--8--9---3---6--8--9---4---|
D|--7--9--11--4---7--9--11--2---|
A|------------------------------|
E|------------------------------|


E|-------------------------------|
B|--12--9--9--7--12--9--9--8--7--|
G|--9---8--8--6--9---8--8--7--6--|
D|--11--9--9--7--11--9--9--8--7--|
A|-------------------------------|
E|-------------------------------|


E|----------------------------|
B|----12----12----12----12----|
G|----------------------------|
D|----------------------------|
A|--10----10----10----10------|
E|----------------------------|


And that's as far as I've gotten.
