I think this is very accurate. I am a pianoplayer, and this fits perfectly with the song.
If you prefer, you could play the Bb instead of the Gm7.
[F]
Give me a second I
I need to get my story straight
[Dm7]
My friends are in the bathroom
getting higher than the empire state
[Gm7]
my lover she's waiting for me
just across the bar
[Bb]
My seats been taken by some sunglasses
[C]
asking 'bout a scar
[F]
and I know I gave it to you months ago
[Dm7]
I know you're trying to forget
[Gm7]
but between the drinks and subtle things
the holes in my apologies
[Bb] [C]
you know I'm trying hard to take it back
Pre-chorus
[Gm7] [Am7]
so if by the time the bar closes
[Dm] [Am/C] [Bb]
and you feel like falling down
[Bb] [C]
I'll carry you home
[Chorus x2]
[F]
Tonight
[F] [Am/E] [Dm]
We are young
[Gm7]
So let's set the world on fire
We can burn brighter
[C] ([C7] or [C6] optional)
than the sun
[The Same as the 1. verse]
Now I know that I'm not
all that you got
I guess that I
I just thought maybe we could find a ways to fall apart
But are friends in back
So let's raise a cup
Cause I found someone to carry me home
[Chorus x2]
[F]
Tonight
[F] [Am/E] [Dm]
We are young
[Gm7]
So let's set the world on fire
We can burn brighter
[C] ([C7] or [C6] optional)
than the sun
[F] [Bb]
Carry me home tonight
[F/A] [C]
Just carry me home tonight
[F] [Bb]
Carry me home tonight
[F/A] [C]
Just carry me home tonight
The world is on my side
I have no reason to run
So will someone come and carry me home tonight
The angels never arrived
but I can hear the choir
so will someone come and carry me home
[F]
Tonight
[F] [Am/E] [Dm]
We are young
[Gm7]
So let's set the world on fire
We can burn brighter
[C] ([C7] or [C6] optional)
than the sun
Pre-chorus
[Gm7] [Am7]
so if by the time the bar closes
[Dm] [Am/C] [Bb]
and you feel like falling down
[Bb] [C] [F]
I'll carry you home tonight
