*I noticed that the other bass tabs for this song are not at
 all how I play it. Not that their wrong but it sounds much
 different to me. Here's my take on it.

Verse/Bridge

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

*The 3a at the end of the verse carries directly back to the
 4a at the beginning to keep the pattern consistent.

Chorus

G-------------------------------------------------| 
D-------------------------------------------------|
A----7--7-7-------------------4--4-4-2-3-4--4-4---|
E-----------(2)-(3)-4--4-4------------------------|

* The 2 and 3 in parenthesis are optional. I usually alternate them for some variation. 
Hope this tab proves helpful. Play On!
