Sofia2017 planning asked about this song from the Peter Pan musical, so enjoy your request, which doubles as your birthday present! I thought it would be fun if, as another way to have fun with the elves in The Elf Situation, James starts singing this to help the elves relax and have more fun, since that's how he, Sofia, and Amber figured out how to stop Queen Elfabelle and Queen Arielf from arguing, since James is right; sometimes it is better to act like a kid rather than a grown-up (and of course the fact that music makes everything better!). Peter Pan the Musical is not mine.

James: Are you ready for today's lesson?

Sofia and Amber: Yes, James!

Queen Elfabelle: This should be interesting.

Queen Arielf: Indeed...

James: Listen to your teacher. Repeat after me:
I won't grow up

Sofia: I won't grow up

James: I don't want to go to school.

Amber: I don't want to go to school

James: Just to learn to be a parrot,

Sofia: Just to learn to be a parrot

James: And recite a silly rule.

Amber: And recite a silly rule

James: If growing up means
It would be beneath my dignity to climb a tree,
I'll never grow up, never grow up, never grow up
Not me!

Amber: Not I

Sofia: Not me!

James: Not me!
I won't grow up

Amber: I won't grow up

James: I don't want to wear a tie.

Sofia: Why would I want to wear a tie?

James: And a serious expression

Amber: And a serious expression

James: In the middle of July.

Sofia: In the middle of July

James (putting his arms around Queen Elfabelle and Queen Arielf): And if it means I must prepare
To shoulder burdens with a worried air
I'll never grow up, never grow up, never grow up
Not me

Queen Arielf (gently shrugging him off but getting into the song): Not I

Queen Elfabelle (moving away from him as she also gets into the song): Not me!

James: So there!
Never gonna be a man,

Sofia/Amber/Queen Arielf/Queen Elfabelle: We're girls!

James: Like to see somebody try
And make me.
Anyone who wants to try
And make me turn into a man,
Catch me if you can.
I won't grow up.

Sofia: Not a penny will I pinch.

James: I will never grow a mustache,

Amber: Or a fraction of an inch.

James: 'Cause growing up is awfuller
Than all the awful things that ever were.
I'll never grow up, never grow up, never grow up,
No sir

Queen Arielf and Amber: Not I

Queen Elfabelle and Sofia: Not me

James: So there!
I won't grow up!

Amber: I won't grow up

James: I will never even try

Sofia: I will never even try

James: I will do just what James tells me

Amber: You want to bet?

James: And I'll never ask him why

Amber: Are you sure about that?

James: Yes!
We won't grow up!

Sofia: We won't grow up

James: We will never grow a day

Amber: We will never grow a day

James: And if someone tries to make it

Sofia: And if someone tries to make it

James: We will simply run away

Amber: We will simply run away

James: I won't grow up!

Sofia: I won't grow up

James: No, I promise that I won't

Amber: No, I promise that I won't

James: I will stay a boy forever

Sofia/Amber/Queen Elfabelle/Queen Arielf: We will stay a girl forever

James: And be banished if I don't!

Amber: And be banished if I don't

James: And Enchancia will always be
The home of youth and joy
And loyalty
I'll never grow up, never grow up, never grow up
Not me!

Queen Arielf and Queen Elfabelle: Not me!

Sofia: Not me!

James: Not me!

Amber: No sir!

Amber/James/Sofia/Queen Arielf/Queen Elfabelle: Not me!
