MAGGIE.
Just listen and repeat after me:

MAGGIE / (JO) / BOTH.
On how to be lovely
(On how to be lovely)
You got to be happy
(You got to be happy)
When you can feel
light and [bad word] 
Then you'll be lovely
as a holiday.

On how to be charming
(On how to be charming)
You got to be merry
(You got to be merry)
If only to weave a spell
And you'll be lovely
As a carousel too.

I (I know you can) show how.
It's (it's all in the) know-how.
And (and once you know) oh how
The world looks good to you
As it should to you.

On how to be lovely
(On how to be lovely)
You got to be jolly
(You got to be jolly)
When you can be fancy-free
And flash a smile that
 [bad word] flocking to see.

You'll be as lovely
As can be.

Do-wee-oo
Do-wee-oo-ee
Do-wee-oo
Do-wee-oo-ee
Do-wee-oo
Do-wee-oo
Boo-diddly-ba-bau! Ee-

Do-wee-oo
Do-wee-oo-ee
Do-wee-oo
Do-wee-oo-ee
Do-wee-oo
Do-wee-oo
Boo-diddly-ba-bau!
(Boo-diddly-ba-bau!)
Boo-diddly-ba-baa-pa-daa!

Can't (can't do it with) make-up
You (you've just got to) wake up
And (and startin' to) take up
life delirious
Nothing serious.

On how to be lovely
(On how to be lovely)
You got to be cheery
(You got to be cheery)
I'll give you a guarantee
You don't need dough
You don't need a college degree.

Make sorrow incidental
(Let joy be monumental)
And you'll be lovely
Do-wee-oo
Do-wee-oo(-ee)
Do-wee-oo
Do-wee-oo(-ee)
You'll be as lovely
As can be
A-do-ee-oo-ee-oo-ee-oo!
