I really hope this is right. I made it by listening to the song and using a video 
of him playing it.

Capo on 6th fret

Strumming pattern for the verse and chorus is;
  
|Bm Bm Bm Bm|G G G G|D D D D|D D A A|


VERSE
Bm                             G
We take this bird in with it's broken leg
D               D    A 
We can nurse it she said
Bm                       G
Come inside for a little lie down with me
D                      D                 A
And if you fall asleep it wouldnt be the worst thing

PRE-CHORUS
           G
And when I wake up
    G
Her make up
         D       D  A
Is on my shoulder
                 G
And tell me if i lie down
         G
Will you stay now
       D        D   A
Let me hold you

CHORUS
         Bm
And if I kiss you
                     G 
Will your mouth read this truth
              D
Darling how I miss you
                        D       A
Strawberries taste like lips do
                Bm
And it's not complete yet 
                G
Musn't get our feet wet
                         D                 D     A
Cos that that leads to regret diving in too soon

         Em                G
And i'll owe it all to you

And if I wake her
                 G                      D      D   A
She'll say "it's late love" go back to sleep

Uncovered by nature
        G
I need safe now
                D                  A
And i need this oak tree with you beside me

CHORUS:
         Bm
But if I kiss you
                     G 
Will your mouth read this truth
              D
Darling how I miss you
                        D       A
Strawberries taste like lips do
               Bm
And it's not complete yet 
                G
Musn't get our feet wet
                        D                 D     A
Cos that that leads to regret diving in too soon

        Em                  G
And of all these things i'm sure of
    Bm                   D
I'm not quite certain of your love
    Em
You make me scream
       G
Then I made you cry
        Bm                             A
When I left that little bird with it's broken leg to die
