How about Nancy's song "Oom Pah Pah" from the musical "Oliver"?

Oom Pah Pah

" Pretty little Sally Goes walkin' down the alley,
Displays a pretty ankle to all of the men.
They could see her garters, But not for free and gratis --
An inch or two, and then She knows when to say when!

ALL:
Oom-pah-pah! Oom-pah-pah! That's how it goes.
Oom-pah-pah! Oom-pah-pah! Ev'ryone knows:
NANCY:
Whether it's hidden, or whether it shows,
It's the same, oom-pah-pah!

She was from the country, But now she's up a gum-tree --
She let a feller feed 'er, and lead 'er along.
What's the use o' cryin'? She's made a bed to lie in.
She's glad to bring a coin in And join in this song!

ALL:
Oom-pah-pah! Oom-pah-pah! That's how it goes!
Oom-pah-pah! Oom-pah-pah! Ev'ryone knows:

NANCY: She is no longer the same blushin' rose
Ever since oom-pah-pah!"
