YES I KNOW, BRIAN GIBSON USES CELLO TUNING ON HIS BASS, BUT THIS IS A STANDARD TUNING 
FOR THOSE THAT CAN'T BE BOTHERED MOST OF THE TIME TO DROP TUNE.

Intro:
G|----------------------------------------------------|
D|----------17-17-17-17-------17----------17----------|
A|----------------------------------------------------|
E|-15-15-15-------------15-15----15-15-15----15-15-15-|

G|-------------------------------------------------|
D|-------------------------------------------------|
A|-------------------------------------------------|
E|-12-12-12-12-13-13-13-13-14-14-14-14-15-15-15-15-|

Repeat around twice before it goes up an octave for the builup thing (is you haven't got 
whammy pedal).

G|-0-0-0-12-12-12-0-0-12-0-0-0-12-0-0-0-|
D|--------------------------------------|
A|--------------------------------------|
E|--------------------------------------|

G|9-9-9-9-10-10-10-10-11-11-11-11-12-12-12-12-|
D|--------------------------------------------|
A|--------------------------------------------|
E|--------------------------------------------|

The rest of the song:

Right, the rest is pretty much these 2 riffs, switch between them as in the song. Cos 
know, you've heard it before, right? You know how it goes.

G|-------------------------------------------------------------------|
D|-------------------------------------------------------------------|
A|-------------------------------------------------------------------|
E|-0-0-0-0-1-1-1-1-2-2-2-2-3-3-3-3-3-0-0-0-0-1-1-1-1-2-2-2-2-3-3-3-3-|

and

G|--------------------------------|
D|2-------3-------4-------5-------|
A|--------------------------------|
E|--0-0-0---1-1-1---2-2-2---3-3-3-|

Finally, the ending:

G|-------|
D|-------|
A|-------|
E|-/15---|

G|---------------------------------|
D|---------------------------------|
A|---------------------------------|
E|-0-0-1-1-1-1-2-2-2-2-3-3-3-3-/15-|

Last note!

G|-------|
D|-------|
A|-------|
E|-/15---| hold that to end it.

Have fun, hope this saves you some drop tuning without losing too much of the original 
quality. Mess about with your EQ a bit if it doesn't sound too good, go for heavy bass in 
main riffs, but a more trebly sound in the intro and ending.
