The Xx - Chained Bass

My favorite song on the album. I was hoping there was a good tab up already for it, but 
that other one didn't sound right so I'll take a stab at it.

First part goes something like this:

G|-----------------------------------------------------------------|
D|-----------------------------------------------------------------|
A|-5-5-5-5-5-5-5-5-3-3-3-3-3-3-3-3-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-|
E|-----------------------------------------------------------------|

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

(personally I like playing the fifth fret on the E instead of an open A, I think it 
sounds better, but whatever you want)

And then there is a variation:

G|-----------------------------------------------------------------|
D|-----------------------------------------------------------------|
A|-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-|
E|-----------------------------------------------------------------|

G|-----------------------------------------------------------------|
D|---------------------------------5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-|
A|-----------------------------------------------------------------|
E|-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3---------------------------------|

These are the two main parts. Listen to the song to hear when to play the right part. 
Hope this helps. If not, hopefully it's in the right direction where someone else can put 
up a better tab.. SLAP DA BASS MON.. sorry.

p.s. this is my first tab, please be gentle..
