Old 97s - Barrier Reef Tabs

I should begin by saying that I'm tone-deaf and this is probably
wrong, so hopefully someone will correct it and complete it, as I
only have the main riff.

Standard (EADGBE low to high) tuning

              *   *   *
E-----------------------
B-----5-----------------
G-5h7---7h8---8---8---8-
D-----------------------
A-----------------------
E-----------------------

(those last 3 notes are staccato)

That's the riff heard in the intro and the first part of verses;
it changes a bit for the remainder of each verse and I can't hear it
well enough to figure it out as yet.  I will try to finish this song
and post it later.  Let me know if I messed up badly.
