I noticed that the bass tab we have of it is in a different key from the way it's 
so I'm going to give it a go in Eb (recorded key)

G-5-3--------------------------------|Repeat 4 times
D----5-------------------------5-----|
A-----6-6b--3------3----3----3-------|
E--------------3-5----5----------0-3-|

G-5---5-3--5-3---5---5-3-------|Repeat 4 times
D---5--------------5-----5-----|Then repeat riff 1 4times
A--------------------------3---|Then repeat riff 2 another 4 times
E------------------------------|then

G---------------------------------------------------------------------------|
D-5----5------5-------5-----5------5-----------------5-----5--------5----5--|
A--3--3---------3---3---------3--3-------2---3--3---3--------3-3--3---------|
E--------0-3------------0-3----------0-3---3-----------0-3------------0-3---|

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

Riff 2 4times, Riff one 4times, riff 2 4times start fading fourth time, then one time 
riff one and fade out completly.  Good luck!  I enjoy comments so throw em at me at Bombean18@*
