[Tommy]
When I grow up
I will be tall enough to reach the branches
That I need to reach to climb the trees
You get to climb when you're grown up

[Bruce]
And when I grow up
I will be smart enough to answer all
The questions that you need to know
The answers to, before you're grown up

[Eric, Alice]
And when I grow up
I will eat sweets everyday on the way to work
And I will go to bed late every night

[Tommy, Bruce, Eric, Alice]
And I will wake up
When the sun comes up
And I will watch cartoons until my eyes go square

[All children]
And I won't care 'cause I'll be all grown up
When I grow up
When I grow up
When I grow up
When I grow up
I will be strong enough to carry all
The heavy things you have to haul around with you
When you're a grown up

And when I grow up
When I grow up
When I grow up
I will be brave enough to fight the creatures
That you have to fight beneath the bed
Each night to be a grown up

And when I grow up (When I grow up)
I will have treats everyday
And I'll play with things that mum pretends
That mums don't think are fun

And I will wake up (I will wake up)
When the sun comes up
And I will spend all day just lying in the sun
And I won't burn 'cause I'll be all grown up

When I grow up
[Miss Honey]
When I grow up
I will be brave enough to fight the creatures
That you have to fight beneath the bed
Each night to be a grown up
When I grow up

[Matilda]
Just because you find that life's not fair
It doesn't mean that you just have to grin and bear it
If you always take it on the chin and wear it
Nothing will change

[Miss Honey]
When I grow up

[Matilda]
Just because I find myself in this story
It doesn't mean that everything is written for me
If I think the ending is fixed already
I might as well be saying
I think that it's ok
And that's not right
