Tabbed by Lee Tyrrell

This is the closest i can get, it's full of variations and they just throw them in at 
points, it seems, but have fun with what i can provide:

~ - Let ring

Intro (and possibly other times)

G-4~----------7~----------|
D-2~----5~----5~----7~----|
A-------3~----------5~----|
E-------------------------|

Main Bass Line:

G----0--2-0-------0--2-0---0-----0--4h5p4/7----7--7---7---|
D-2---------2--------------------------------0------0---0-|
A-------------3----------3--------------------------------|
E-----------------------------3---------------------------|

Variation:

G----0--2-0-------0--2-0---0-----0--7/4-0-2~-|
D-2---------2-----------------------------0~-|
A-------------3----------3-------------------|
E-----------------------------3--------------|

During Xylophone Parts:

G---4-0-4---4-0----0-4---4---2-------0---0---2~--2--2-----2---|
D-2-------2--------------------------------4-0~--------0----0-|
A---------------3------3---3---3---2---2----------------------|
E--------------------------------3----------------------------|

The bass doesn't actually play this, guitar and xylophone do, but, seeing as though you 
play it on bass, it's worth knowing, and if you get bored of the main riff you can stick 
in as a substitute.
