This isnt the bango version played on the album, but the live version he
 plays on guitar, so youtube it if you havent heard it.

Im not going to write out the picking pattern, becuase its long and
 tedious, but its similar to others he does with some variations. Again,
 there are some great videos on youtube so you can see how he picks it.

Capo on the 4th fret or so.

Intro
D ---0----0----0---0----------------------------------|
A ---4b---0----0---0----------------------------------|
#F---0----0----0---1----------------------------------|
D ---0----2----2---0----------------------------------|
A ---0----4----3---2----------------------------------|
D ---0----x----x---x----------------------------------|

These four chords are repeated through the verses, and are
the bulk of the song. The ( 4b ) is a C# thats is bent slightly - youl
get it once you hear it.

The chorus then goes:

    Ooo when I dive into the waterrr . . . .
D ---0-------------0----------0---------|
A ---0-------------0----------4b--------|
F#---5-------------1----------0---------|
D ---0-------------2----------0---------|
A ---0-------------0----------0---------|
D ---5-------------0----------0---------|

  Ive raised the bottom to be saved, its just a shallow grave
D ---0------------------------0-------------------------------|
A ---0------------------------0-------------------------------|
F#---5------------------------1-------------------------------|
D ---0------------------------2-------------------------------|(intro chords)
A ---0------------------------0-------------------------------|
D ---5------------------------0-------------------------------|


Thats it, good luck!
