[Verse 1: Cy]
You don't know me but my name's Cy
I'm just the O'Hare delivery guy
But it seems like trees might be worth a try
So I say let it grow

[Verse 2: Dan & Rose, Both]
My name is Dan
And my name's Rose
Our son, Wesley, kind of glows
And that's not good, so we suppose
We should let it grow

[Chorus: Mrs. Wiggins & Crowd]
Let it grow, let it grow
You can't reap what you don't sow
Plant a seed inside the earth
Just one way to know its worth
Let's celebrate the world's rebirth
We say let it grow

[Verse 3: Marie & Grammy Norma]
My name's Marie and I am three!
I would really like to see a tree
La-la-la-la-la-la-la-la-la-la-lee
I say let it grow
I'm Grammy Norma, I'm old and I've got gray hair
But I remember when trees were everywhere
And no one had to pay for air
So I say let it grow
[Chorus: Crowd]
Let it grow, let it grow
Like it did so long ago
It is just one tiny seed
But it's all we really need
It's time to change the life we lead
Time to let it grow

[Verse 4: O'Hare]
My name's O'Hare, I'm one of you
I live here in Thneedville too
The things you say just might be true
It could be time to start anew
And maybe change my point of view
Nah! Haha

[Bridge: O'Hare, Marie & Cy]
I say let it die!
Let it die, let it die
Let it shrivel up and—
Come on! Who's with me? Huh?
Nobody
You greedy dirtbag!

[Chorus: Crowd]
Let it grow, let it grow
Let the love inside you show
Plant a seed inside the earth
Just one way to know its worth
Let's celebrate the world's rebirth
We say let it grow
Woah, woah, woah, let it grow, let it grow
You can't reap what you don't sow
It's just one tiny seed
But it's all we really need
It's time to banish all your greed
Imagine Thneedville flowered and treed
Let this be our solemn creed
[Outro: Crowd]
We say let it grow (In Thneedville)
We say let it grow (It's a brand new dawn)
We say let it grow (In Thneedville)
We say let it grow (It's a brand new dawn)
