The only other tab on here is in standard tuning and therefore doesn't sound
right when you play with the song, Brian Gibson uses standard cello tuning for
most songs. (CGDA)

Clean Bass/ Distorted Bass                                H
A---0--0----0-7-5-3--3----3-5-7-0--0----0-5-5-3--3----3-5-7-5-|
D---0--0----0-7-5-3--3----3-5-7-0--0----0-5-5-3--3----3-5-7-5-|
G-------------------------------------------------------------|
C-------------------------------------------------------------|

^^This is played for the majority of the song, with variations occasionally.
It is played clean a few times then the distortion is turned on.



This riff kicks in at about 3 minutes into the song.
A--------------------|
D-10-----8-10-8-10-8-|
G--------------------|

Then the riff get simplified to this.

C----------------|

This is then the ending riff

Hope this tab helps a little more than the other one does, notify
me if there is anything that needs to be edited!
