From the sheet music at The National Library of Australia:

YOU CAN'T WALK BACK FROM AN AEROPLANE (SO WHAT ARE YOU GIRLS GONNA DO?)
Words and music by Irving Bibo and William B. Friedlander, ©1927.

1. [GIRL:] When a maiden seeks romance,
There are times she takes a chance,
Even though her boyfriend loves her truly.
I've had my experience,
Therefore as a consequence,
I know boys are bound to get unruly.
Walking back from auto rides, I'll say I've had my share,
But soon the boys will take us out a-riding through the air—

CHORUS: And you can't walk back from an aeroplane,
So what are we girls gonna do?
When all these future Lucky Lindys want some squeezin',
A girl who has good sense will have to listen to reason,
For there's air, air ev'rywhere,
And not a drop to walk on; it's true.
Oh, what a time the married men will have, I declare!
Their wives won't have a chance to have them watched way up there,
And you can't walk back from an aeroplane,
So what are we girls gonna do?

2. [BOY:] Boys, we've had it mighty tough.
Girls have fooled us long enough,
And we've let them go on and deceive us.
They want food and then besides,
They want nice long auto rides,
But just try and kiss them and they leave us.
After they get all they want, they walk home; they don't care,
But, girls, we soon will take you out a-riding through the air—

CHORUS: And you can't walk back from an aeroplane,
So what are you girls gonna do?
Now just suppose he takes you flying o'er some ocean.
If he suggests a kiss, you'll have to second the motion,
For there's air, air ev'rywhere,
And not a drop to walk on; it's true.
Why, even boys who never in their whole lives were rude
Are bound to be affected by the high altitude,
And you can't walk back from an aeroplane,
So what are you girls gonna do?

A lot of girls will scream: "You stop or out I will go,"
But if he doesn't stop, she'll stay when she looks below,
'Cause you can't walk back from an aeroplane,
So what are you girls gonna do?
