None of the other chords seemed to be actually right for this song (although they 
did sound good, just not right.)
So I did it myself! :) I think this is pretty much what he plays. 

The first half of the first verse has some cute little chords like: 

    G    Bm  A             
E|-----|---|----|          As far as I can tell, but they 
B|--3--|-3-|-3--|          sound good as normal chords and
G|--2--|-2-|-2--|          as bar chords as well. Take your
D|--0--|-0-|-2--|          pick! 
A|--0--|-2-|-0--|
E|--3--|---|-0--|


      D                      
She's reinventing loving me
          G                         Bm
When we're resembling cutlery on the sofa
                         A
It must have been about 5.01
       G
Like my blue ripped jeans
       D    
And my eyes are closed and I'm way too tired
G
Hoody still smells of the beach bonfire
      Bm
On the sofa, where we lay
A                 G
  I wanna stay inside all day

         Em      G         D       A
And it's cold outside, again
          Em      G
And we're both so high

        Bm                 G            D         D
We could fly to Berlin, Tokyo or Jamaica
        Bm              
We can go where you want
           G                  D          
Say the word and I'll take ya
D                           Bm A G  
But I'd rather stay on the so-----fa
         Bm A G             D
On the so------fa, with you

D
  When the morning comes
G
We're not watching Formula I
Bm
It's not what we breathe for
A                        G
So kick off the day with Friends on T4
D 
  Two, boiled and brew
G
Two sugars ain't too sweet for you
Bm
 On the sofa, where we lay
A               G
I wanna stay inside all day

        Em      G         D        A
And it's cold outside, again
         Em          G
And we're still so high



        Bm                 G            D         D
We could fly to Berlin, Tokyo or Jamaica
        Bm              
We can go where you want

Say the word and I'll take ya

But I'd rather stay on the so-----fa
         Bm A G             G
On the so------fa, with you

G                A         Bm       D
 And it feels like I'm flying
G             A
 And it feels like
        Bm              G              D      D
We could go to Berlin, Tokyo or Jamaica
           Bm                   
Through the streets of New York
             G                D           D
That is where I will take ya
       Bm           
Paris, Rome, to Rio
         G                 D           D
Passing through Las Vegas
       Bm           
We can go where you want
        G                    D            
Say the word, and I'll take ya
D                            Bm A G
But I'd rather stay on the so------fa
         Bm A G
