Here's the brilliant brand new single from Keane! Based on this live version:

Yes, apparently Keane do also use guitars! :)

----

The guitar plays a plain D on the intro and chorus, but you can play the
following chord sequence (strumming 4 times each) for an acoustic 
version more similar to the piano riff: D   Dsus2  Dmaj7  D

The chord at the end of the verse (D*) sounds like a Bm on the piano, 
but in the video he plays a D on the guitar.

Intro: D   Em7  F#m  D   Em7  Asus4

D                              Em                                Bm
Something's crept in under our door, silence soaking through the floor
(D)                         Em                              Bm
Pinching like a stone in my shoe, some chemical is breaking down the glue
Em                        D*
That's been binding me to you

D                            Em7
Oh, I feel like I just don't know you anymore
F#m                                    D
I've been burnt and I've been wrong so many times
                        Em7                      Asus4                   D
We walk in circles, the blind leading the blind, we've been disconnected somehow
                     Em7
There's an invisible wall between us now
F#m                                    D
I've been burnt and I've been wrong so many times
                        Em7                     Asus4
We walk in circles, the blind leading the blind

(D)                                        Em
Well I thought that love watched over this house
                                   Bm
But you're boarding up the windows now
      (D)                      Em                              Bm
We're leaning on each other so hard, tied so tight we wound up miles apart
Em                      D*
Making simple things so hard

Oh, I feel like I just don't know you anymore
I've been burnt and I've been down so many times
We walk in circles, the blind leading the blind, we've been disconnected somehow
There's an invisible wall between us now
I've been wrong and I've been down so many times
We walk in circles, the blind leading the blind

Interlude: Gm  D   Gm   D

G                   Bm       Asus4   G                            Bm  Asus4  G
I see the landscape change before my eyes, the features I've been navigating by
                  D      Asus4 Em7
Nothing looks the way it did before
             Asus4                         D
I don't know where to look or what to look for

D                            Em7
Oh, I feel like I just don't know you anymore
F#m                                   D
I've been burnt and I've been down so many times
                       Em7                      Asus4                   D
We walk in circles the blind leading the blind, we've been disconnected somehow
                     Em7
There's an invisible wall between us now
F#m                                   D
I've been wrong and I've been down so many times
                       Em7                      Asus4                   D
We walk in circles the blind leading the blind, we've been disconnected somehow
Em7    F#m                         D              Em7     Asus4       D
              There's an invisible wall   between us now
