It's a country song about 2 brothers, they both go to war or something like that, and then the song goes like, one looks at the other and says you first, ill see you on the other side... never thought it'd be you first, then it says something about how you find real heroes when you say you first

I don't know if those are the exact lyrics, buuut yeah.

And both the brothers are wounded I think

That is Mac McAnally entitled, "You First".

Here are the lyrics:

You First

The river looked much wider
Than it ever seemed before
Even though we crossed
A hundred times or more
We were scared
So we dared each other

You first
And I'll be right behind you
You first
I'll meet you on the other side
The nature of a hero
Requires a leap of faith
Find out what you're made of
When it's your time to say
"You first"

The chopper drops the ladder
In the middle of the war
Sergeant says there's only room
For just one more
Two wounded brothers
One says to the other

You first
And I'll be right behind you
You first
I'll meet you on the other side
The nature of a hero
Requires a leap of faith
Find out what you're made of
When it's your time to say
"You first"

Now, I'm standing over you
All these years that we've been through
I wish it could be me
I never thought that it might be

You first
But I'll be right behind you
You first
I'll meet you on the other side
You always were my hero
Here's my leap of faith
Find out what you're made of
When it's your time to say
"You first"
