Phineas
It been a long, long day
And there were moments when I doubted

Isabella
That we'd ever reach the point
Where we could laugh and sing about it

Both
Now the sun has set on this,
Another extraordinary day
And when it comes around again
You know I'll say
Tell me what you wanna do today
All we need is a place to start
If we have heart, we'll make it
'Cause we're not messin' around (we're not messin' around)
Yes we can dream it, do it, build it, make it
I know we can really take it
To the limit before the sun goes down

Phineas
As soon as you wake up you gotta make your move

Isabella
Don't miss the beat, just get into the groove

Both
The sun is shinin', there's a lot that you can do (a lot that you can do)
There's a world of possibilities outside your door
Why settle for a little, you can get much more
Don't need an invitation, every day is new
Yes, it's true
Summer belongs to you (summer belongs to you)
Summer belongs to you (summer belongs to you)
Summer belongs to everyone, so have some fun
There's nothing better to do
Summer belongs to you

Candace
All right, I'm taking a verse.

Phineas
Be my guest.

Candace
I traveled halfway 'round the world
And almost turned and ran away
But you helped me get my courage back
So now I've got to say
That though I've often thought of you
As just a nuisance and a bother
Today I can't imagine
Having better little brothers
And you gotta believe in something
So today I believed in you
And you came through, we made it
I've never been so proud (never been so proud)
I know at first it seemed implausible
But we accomplished the impossible
Now there's something that I've got to say out loud
Time is what you make of it, so take a chance

Phineas
That's it!

Candace
Life is full of music so you ought to dance

Phineas
She's got it!

Candace
The world's a stage and it is time for your debut (it's time for your debut)

Phineas
By Jove, I think she's got it!

Candace
Don't waste a minute sitting on that chair

Phineas
Yeah!

Candace
The world is callin' to you, just get out there

Phineas
That's what I'm talking about!

Candace
You can see forever so your dreams are all in view

Phineas
Yes it's true

All
Summer belongs to you (summer belongs to you)
Summer belongs to you (summer belongs to you)
Summer belongs to everyone, so have some fun
There's nothing better to do

Phineas
Summer belongs to you (summer belongs to you)
Summer belongs to you (summer belongs to you)
Summer belongs to boys and girls all around the world
We wouldn't say it if it wasn't true
Summer belongs to you (summer belongs to you)

Ferb
Baby, baby, baby, baby

Both (Phineas & Isabella)
Summer belongs to you (summer belongs to you)
Summer belongs to you (summer belongs to you)
Whatever you want to do, you make the rules
You got the tools to see it through
Summer belongs to you (summer belongs to you)
Summer belongs to you (summer belongs to you)
Just remember that you can do it and when you're through it
Will change your point of view
Summer belongs to you!
