Tuning: Standard

I think it goes something like this. The progression below pretty much repeats 
throughout the song.

----x-----x-----x-----x-----x-----x-----x-----x-|
----6-----6-----x-----x-----x-----x-----x-----x-|
----6-----6-----3-----3-----5-----5-----3-----3-|
----6-----6-----4-----4-----6-----6-----4-----4-|
-4--4--4--4-----4-----4-----6-----6-----4-----4-|
-x--x--x--x--2--2--2--2--4--4--4--4--2--2--2--2-|
