[Time Spent Together Part 1: Aaron Daniel Jacob]
Summer is done, and we've had our fun
But this isn't the end of our story
So, for nostalgia's sake, let's just take a break
Sit back and take inventory
We've done so many wondrous things, and there's still so much to do
But I make the most of every day whenever I'm with you because
It's not about the summer sun
Or even all the things we've done
It's not about the change in the weather
It's just about the time we spend
With our family and with our friends
It's just about the time spent together
It's just about the time, not the weather
It's just about the time spent together

[Curtain Call Verse 1: Phineas Flynn, Candace Flynn, & Buford]
It started out simple with a cool roller coaster, an awesome beach party, then we raced our cars!
We were one-hit wonders with a big hit song
And in a special two-parter, we sent Candace to Mars!
We built treehouse robots, hunted Bigfoot and a mummy
Got the band back together and our parents, too!
When my brothers got busted, it was only a dream!
But who had that dream? Was it Perry or you?
Actually, I think my dream was inside of Perry's dream
My mind is blown
[Curtain Call Chorus]
All
There's been a hundred and four days of summer vacation!
We've had a lot of fun and sung a lot of songs!
So now it's time for a big celebration
'cause it's been a great summer and we thank you all for
Coming along!
Thank you for coming along!

[Curtain Call Verse 2: Dr. Doofenshmirtz, All]
I'm six foot two and I fight a little platypus
You'd think I'd be victorious just every now and then
I've had a whole lotta schemes and a lot of -inators, but I fail
Over and over and over and over and over and over again!
Aw, but it was fun, though!

[Curtain Call Verse 3: Phineas Flynn, Isabella]
We spent a day fighting pharmaceutical zombies
Would've solved cold fusion but did fashion instead
We met Klimpaloon and Meep and the Lake Nose Monster
But we're still baffled by the giant floating baby head
We played Hockey Z-9 and Football X-7
We went 'round the world and to the very edge of space
We met our doppelgangers in the second dimension
Isabella kissed me but I got my mind erased!
Wait, what?You just wait ten years!
[Curtain Call Chorus: Phineas Flynn]
There's been a hundred and four days of summer vacation
We've had a lot of fun and sung a lot of songs!
So now it's time for a big celebration
'cause it's been a great summer so we thank you for
Coming along!**
Thank you for coming along!
Thank you for coming along!
Thank you for coming along!
Thank you for coming along!
Thank you for coming along!
Thank you for coming along!
Thank you for coming along!
Thank you for coming along!
Anyone want some pie?
Yes. Yes, we do!

[Time Spent Together Part 2: Aaron Daniel Jacob]
It's just about the time we spent together
It's just about the time spent together with you
