Okay, I got this bass line down. 

Part I
G|-------------------
D|-------------------
A|--2-3-2-2-3-2-2-3-2
E|-3-3---3-3---3-3---3
Guitar does that twice, then bass comes in and plays it 4 times.
Part II
G|-----------------------------------------------
D|-----------------------------------------------
A|----5h7---5h7---3-2-0-3-3-2-0------5h7---5h7---
E|-0-0---0-0-----------3-------3--0-0---0-0------

G|------------------------------
D|------0-3h4-0-3h4-0-3h4-------
A|-3-2-3-----------------3-2-0--
E|------------------------------
Listen to the song to get it. There are little add-ons on some
parts, but for the sake of confusion I'll leave them out.

Okay, there's this bass line in the middle of the song. 
Sounds tough, but I got it.

G|---------------Play this FAST.
D|-5-3-0-3-0-----
A|-----------3-2-
E|--------------- Then Part I

Here's the order:

Intro(guitar plays Part I twice, then bass joins in and plays it
twice)

Part II - Once
Part I  - Twice
Part II - Once
Part I  - Twice(this has the hard bass line)
Whisper part(Whole lot of Part I's)
Part II - Once
Part I  - Twice(outro)

Remember, listen to the song to figure it out. E-mail me if you
had any problems with the tab, it would help me out.
