Found / Tonight lyrics --- Ben Platt in bold and Lin-Manuel Miranda underlined

We may not yet have reached our glory
But I will gladly join the fight
And when our children tell their story
They'll tell the story of tonight
They'll tell the story of tonight
Tonight

Have you ever felt like nobody was there?
Have you ever felt forgotten in the middle of nowhere?
Have you ever felt like you could disappear?
Like you could fall, and no one would hear?

Well, let that lonely feeling wash away
All we see is light
'Cause maybe there's a reason to believe you'll be okay
For forever
'Cause when you don't feel strong enough to stand
You can reach, reach out your hand

And oh
Raise a glass to freedom
Something they can never take away
Oh
No matter what they tell you
Someone will coming running
To take you home
Raise a glass to all of us
Tomorrow there'll be more of us
Telling the story of tonight
Out of the shadows

The morning is breaking (they'll tell the story of tonight)
And all is new
All is new
All is new
It's only a matter of
Time

Even when the dark comes crashing through
When you need a friend to carry you
When you're broken on the ground
You will be found
So let the sun come streaming in
'Cause you'll reach up and you'll rise again
If you only look around
You will be found

And when our children tell their story
You will be found
They'll tell the story of tonight
Whoa
No matter what they tell you
Tomorrow there'll be more of us
Telling the story of tonight
The story of tonight
