This is a new song (2010) by Kings of Leon. I've only heard it through various 
YouTube videos, so it could change before it's on their new studio album. Anyways, 
here's what I've got.

Intro (and some verse):

Lead: Matthew (Electric)
e|---------------------------------------------------------|
B|--12----12---12---7---7---7---5--5---5--3--3------3------|
G|---12----12--------7---7-------5--5------4--4--2h4-4-0---|
D|---------------------------------------------------------|
A|---------------------------------------------------------|
E|---------------------------------------------------------|

Rhythm: Caleb (Acoustic)

Basically, he plays a G chord throughout the whole song, but if you want to add 
something to it, you can play this sequence of chords (listen to the song for the strumming):

e|-3--2--0--x-----------------------------------------|
B|-0--0--0--3-----------------------------------------|
G|-0--0--0--0-----------------------------------------|
D|-0--0--0--0-----------------------------------------|
A|-2--2--2--2-----------------------------------------|
E|-3--3--3--3-----------------------------------------|


During the end chorus the bass throws in a B and C chord, so to play along play this:

e|-----------------------------------------------|
B|-----------------------------------------------|
G|-----------------------------------------------|
D|--555555---999999---1010101010---55555---------|
A|--555555---999999---1010101010---55555---------|
E|--333333---777777----8-8-8-8-8---33333---------|

FIlls:

Matthew

B|---15-12----15--15b17-----15--------------------|
G|----------------------------12------------------|
D|------------------------------------------------|

Ending Solo:

Basically fiddle around with a G Minor Pentatonic Scale:

e|--------------------------------------------------------------------|
B|------------------------------------12---12---12---12---------------|
G|-14b-14b-14b-14b-14b-14-12--12---14b---14b--14b--14b--14--12-12-----|
