This is based off the officially released acoustic session by Alex and Matt on 
YouTube at Avatar studios (http://www.youtube.com/watch?v=Fn2OfRGbxwc).

Chords: Alex uses the open version of Gm, with his thumb on 3rd fret on E string, 
but if that's a hard shape to grasp, standard Gm sounds perfectly fine
    E A D G B E
Gm  3 5 5 0 3 3
        or
    3 5 5 3 3 3

D#m x 6 8 8 7 6

Cm  x 3 5 5 4 3

D   x x 0 2 3 2

Intro and chorus have the same rhythm, which is as follows:
Gm (1 bar) D#m (1/2 bar) Cm (1 1/5 bars)

Intro: Gm D#m Cm

Verse 1:
Gm                          D#m        Cm
Have you got colour in your cheeks?

Cm                                      Gm
D'you ever get that fear that you can't shift

Gm
The type that sticks around like summet in your teeth?

Gm        D#m          Cm
Have some aces up your sleeve?

Cm                              Gm
Have you no idea that you're in deep?

Gm
I dreamt about you nearly every night this week

Gm       D#m             Cm
How many secrets can you keep?

Cm                                       Gm
'Cause there's this tune I've found that makes me think of you somehow 

Gm
And I play it on repeat

D#m     Cm
Until I fall asleep

Cm                    D
Spillin' drinks on my settee 

Pre-chorus:

D#m
Do I wanna know?

D#m
If this feelin' flows both ways?

       Cm
Sad to see you go

Cm
Sorta hopin' that you'd stay 

        Gm
Darlin' we both know

Gm
That the nights were mainly made for sayin' things that you can't say 

Gm
tomorrow day


Chorus:

                 Gm
Crawlin' back to you

Gm              D#m
Ever thought of callin'

Cm
When, you've 'ad a few 

Cm
'Cause I always do

Cm
Maybe I'm too

Cm         Gm 
Busy bein' yours, to fall for, somebody new

Gm
Now I've thought it through,

Gm
Crawlin' back to you.

Verse:

D#m (1 strum)       Cm (1 strum)
So 'ave you got the guts?

                       Cm (1)        Gm (1)
Been wonderin' if your heart's still open

       Gm (1)     Gm (1)
And if so I wanna know what time it shuts

D#m (1)         Cm (1)
Simmer down and pucker up

                            Gm (1)
I'm sorry to interrupt it's just I'm constantly on the cusp of 

Tryin'

D#m       Cm                              Gm           (stop)
To kiss you, but I dunno if you, feel the same as I do

Gm             D#m     Cm
   We could be together, 

Cm            D
If you wanted to..

Pre-Chorus 2: repeat pre-chorus 1

Chorus 2: repeat chorus 1

Outro verse:

D#m                                         Cm

Darlin' we both know, that the nights were mainly made for sayin' things that 

Gm
