May did some few mistakes, APOLOGIES. But, yeah, this are the chords for Glee's 
version of We are young. It was amazing. :) 

G
Give me a second I

I need to get my story straight
Em
My friends are in the bathroom
                                                   D
getting higher than the empire state
    C
my lover she's waiting for me

just across the bar
                           D
My seats been taken by some sunglasses

asking 'bout a scar
           G
and I know I gave it to you months ago
Em                                             C
I know you're trying to forget
 D   
but between the drinks and subtle things
                               
the holes in my apologies
         D
you know I'm trying hard to take it back
                    Em                 D
so if by the time the bar closes
              Em         C         D
and you feel like falling down
      Em            D
I'll carry you home 

G
Tonight
             Em
We are young
                           C
So let's set the world on fire

We can burn brighter 
              D
than the sun

Tonight
we are young
so let's set the world on fire
we can burn brighter
than the sun

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 

Tonight
We are young
So let's the set the world on fire
we can burn brighter
than the sun

Tonight
We are young
so let's set the world on fire
we can burn brighter
than the sun

Carry me home tonight
Just carry me home tonight
Carry me home tonight
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 

Tonight
We are young
So let's set the world on fire
we can burn brighter
than the sun

Tonight
We are young
so let's set the world on fire
we can burn brighter
than the sun

So if by the time the bar closes
and you feel like falling down
I'll carry you home tonight
