Kings Of Leon - Dusty Bass

I watched a few live videos and as far as i can gather he play the bass like this:-

Main riff, comes in on 2nd verse i think,
G-----------------------------|
D-----------------------------|
A---------------5-------------|
E--0---0---5/7----3-- 0-3-3-3-|


occaisionly he does this:-
G-----------------------------|
D-----------------------------|
A---------------5-------------|
E--0---0---5/7----3-- 0-3-2-0-|

listen to the song for the exact timing etc,
