From the sheet music at York University (Toronto):


KEEP YOUR SKIRTS DOWN, MARY ANN
Words by Andrew B. Sterling, music by Robert King & Ray Henderson, ©1925.)

1. "Mary Ann, Mary Ann,
I'm ashamed your name's McCann."
"What's the matter, mama dear?"
"Mary Ann, come over here.
Faith, is that the dress you bought?"
"Mother dear, they wear 'em short."
"You'll get pinched if you get caught.
Take this tip from me:

CHORUS 1: Keep your skirts down; keep your skirts down.
Keep your skirts down, Mary Ann.
Just because you have a dimple on your knee,
Don't think it was put there for the world to see.
Keep your skirts down; keep 'em way down
When you sit down, if you can.
You'd make any man at all a nervous wreck.
Remember you can wear your beads around your neck.
Keep your skirts down; keep your skirts down.
Going up, keep 'em down, Mary Ann.

2. "Mary Ann, Mary Ann,
Faith, you'll never get a man."
"Oh! I'll grab one, mama dear."
"Mary Ann, just listen here:
Men like the old-fashioned kind."
"Mama dear, some men aren't blind."
"Not with you to walk behind.
When the north wind blows—

CHORUS 2: Keep your skirts down; keep your skirts down.
Keep your skirts down, Mary Ann.
You won't catch a fellow with your stockings rolled.
All that you will ever catch will be a cold.
Keep your skirts down; keep 'em way down
When you sit down, if you can.
You must stop the traffic when you cross Broadway.
It's getting tougher for the blind men ev'ry day.
Keep your skirts down; keep your skirts down.
Going up, keep 'em down, Mary Ann.
