This is just what I can gather from the live videos shown so far, Frank hasn't 
actually released the song yet. :)



VERSE 1 (chords at the start are palm muted until chorus)
                   Em
Man, we used to be brothers
D                G
 Superheroes and warriors
E                    D
Cowboys and Indians, train drivers
G
Everything rolling through the endless summers
               Em
But everything changes
D                             G
 You got married, had children
      Em
And I don't have your number
    D                          G
The one I can remember is that place you used to live with your parents


CHORUS (open strumming)
           C                D         Em          G        D
But in the stillness of the moment it takes for a Polaroid picture

To capture our faces forever and
    C                  D            Em
The world has turned a touch on its axis
        G          D
And the only thing certain is

That everything changes


VERSE 2 (PM)
                    Em
And they closed the Astoria
D                   G
 At the end of last summer
    Em
The place we earned our pedigrees
D
Scene of our victories
G
Sanctuary in the centre of London
                       Em
Now they're building a railway
D                           G
 To track the vanquished to Versailles
        Em
And the singalongs go on
            D
But they're singing different songs
   G
In rooms that we don't know on the other side of the city


CHORUS (open)
           C                D         Em          G        D
But in the stillness of the moment it takes for a Polaroid picture

To capture our faces forever and
    C                  D            Em
The world has turned a touch on its axis
        G          D
And the only thing certain is

That everything changes


BRIDGE
                C
So honey I just need a little time
   Em                   D
To take a little time today
   C                           Em
To savour all the triumphs and tragedies
                  D
Before they slip away
                  G (PM this section)
Before they slip away

    G
Let go of the little distractions
     D
Hold close to the ones that you love
           C
Because we won't all be here this time next year
             Em                    D
So while you can take a picture of us
    G
Let go of the little distractions
     D
Hold close to the ones that you love
           C
Because we won't all be here this time next year
             Em                    D
So while you can take a picture of us

(open)
                G
Take a Polaroid picture
                D
Take a Polaroid picture
                C
Take a Polaroid picture
                Em      D
Take a Polaroid picture
                           G
Oh, please take a Polaroid picture
                D
Take a Polaroid picture
                  C
Take a picture of us to show
                   Em            D
We all want you to see where the time goes

CHORUS (open picking)
          C                D
So in the stillness of the moment
     Em
Make sure you take a Polaroid picture

And keep it with you forever to
C                    D
Remind yourself that everything changes
                  
But there was this one time

Man there was this one time
                  A7 (strummed, let ring)
When things were okay...

And that's it. Sorry for any mistakes but it sounds ok to me! :)
