I just discovered these guys yesterday, and I am listening to this song for
the first time right now.  I'm gonna tab it for you. I think these guys are
pretty damn good and I like this style of rocking alt-country they are
making.  Here we go

Standard Tuning - This song is just the same 3 chords with a catchy riff
USE POWER CHORDS THROUGHOUT
Intro and Main riff:  Repeat this twice as intro

e------------------------------------------------------------------------|

D-----4-2-4p2---2-4-----4-2-4p2---2-----4-2-4p2---2-4--------------------|

E--2-----------------2---------------2-----------------------------------|

G--2-2-2-2--4-4-4--------------------------------------------------------|
D--2-2-2-2--4-4-4--------------------------------------------------------|
A--0-0-0-0--2-2-2--0-----------------------------------------------------|
E------------------------------------------------------------------------|

Verse:  Below note the A note after 7 F# power chords.  The third time
notice no A, it just moves straight to the A power chord after 8 F#'s

  F#                F#               F#               A        B

A--4-4-4-4-4-4-4----4-4-4-4-4-4-4----4-4-4-4-4-4-4-4--7-7-7-7--9-9-9--7--|
E--2-2-2-2-2-2-2-5--2-2-2-2-2-2-2-5--2-2-2-2-2-2-2-2--5-5-5-5--7-7-7--5--|

Chorus:

F#                 A       B
Maybe down by the old oak tree
F#                            A    B
They'll cut my hair when they bury me
F#             A      B
Pack me up and set me out to sea


Then return back to main riff and repeat verses and riff and chorus as
necessary.

The guitar/harmonica solo/break thing just repeats the F#, A, B progression
with some basic and simple stuff going on over top which I'm not going
to tab.

This should lay it out for you fairly well.  I was going to pull the lyrics
off of a website, but they are terribly wrong so you will have to decipher
those for yourself.  A cool and very simple riff.

Enjoy,
