I made this listening to the ukulele version off of their latest EP but it works 
with Narrow Stairs version also. It sounds better too.

C/G       Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
Oh, my talking bird
C/G             G7           Fmaj7 (sus2 when it sounds right) 
Though you know so few words
C/G          Cmaj7/G    Fmaj7 (sus2 when it sounds right)
They're on infinite repeat
C/G                   G7           Fmaj7 (sus2 when it sounds right) 
Like your brain can't keep up with your beak

C/G                 Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
And you're kept in an open cage
C/G               G7           Fmaj7 (sus2 when it sounds right) 
So you're free to leave or stay
C/G             Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
And sometimes you get confused
C/G             G7           Fmaj7 (sus2 when it sounds right)  
Like there is a hint that I'm trying to give you

Dm7
And the longer you think
G7
The less you know what to do

C/G            Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
It's hard to see your way out
C/G               G7           Fmaj7 (sus2 when it sounds right) 
When you live in a house in a house
C/G          Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
'Cause you don't realize
C/G                  G7           Fmaj7 (sus2 when it sounds right) 
That the windows were open the whole time

C/G         Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
But oh, my talking bird
C/G                     G7           Fmaj7 (sus2 when it sounds right) 
Though your feathers are tattered and furled
C/G            Cmaj7/G    Fmaj7 (sus2 when it sounds right) 
I'll love you all your days
C/G                        G7           Fmaj7 (sus2 when it sounds right) 
'Til the breath leaves your delicate frame

Dm7
It's all here for you
G7
As long as you choose to stay
C/G         Cmaj7/G    Fmaj7 (sus2 when it sounds right)
Heeeeeeeeeyyyyyyyyyyyyyy
Dm7
It's all here for you
G7
As long as you don't fly away
