The other tabs weren't the greatest representation of the song in my opinion. After 
stumbling around youtube and watching dave play a few time i got the gist of it pretty quick.

Drop D Tuning

PART ONE
Dave sings the tribal intro over this part. Just keep playing it over a few times.

E ---------------------------------------------------|
B ---------------------------------------------------|
G ---------------------------------------------------|
D ---------------------------------------------------|
A ----3h5--5--5-3-5--5--5-3h5--5--5-3-5--5--5-3------|
D ----0-0--0--0-0-0--0--0-0-0--0--0-0-0--0--0-0------|

PART TWO
Here Dave starts singing actual words.

E---------------------------------------------------|
B---------------------------------------------------|
G---------------------------------------------------|
D---------------------------------------------------|
A----5--5--5-5--5--5--5--3h5--5--5-3-5--5--5-3------|
D----4--4--4s5--5--5--5--0-0--0--0-0-0--0--0-0------|

                " If    I     Go ................"

PART THREE
Then after a couple verses when Dave goes to sing really high you switch it up to this.

E---------------------------------------------------|
B---------------------------------------------------|
G----4--4-4-4-4-4-----------------------------------|
D----4--4-4-4-4-4--5--5-5-5-5-5-5-------------------|
A----2--2-2-2-2-2--5--5-5-5-5-5-5-------------------|
D----4--4-4-4-4-4--5--5-5-5-5-5-5-------------------|

           "I'm on bended knee father please."

Then you go back to parts one and two. These are all the tabs for the guitar. Give the 
song a listen or two to match it all up right. Good luck!
