Taking the girl in the blue dress from the chorus, I mix two separate shanties to end up with this, which I adapted from Elise's post in this thread. It keeps the glorious tune, but loses all the racist bits

I never seen the like since I bin born,
There's a pretty gal asleep with a blue dress on
Oh, Johnny come down to Hilo!
Oh, poor old man!

Oooh! wake her! Oooh! shake her!
Ooooh! wake that gal with the blue dress on!
When Johnny comes down to Hilo!
(Oh) poor old man!

This gal she looked so good to me,
'Cos I'd bin ten long months at sea,

Them Hilo girls they act so fine
They ain't got Jesus on their minds

My girl's got class, my girl's got style,
For a dollar a time it's all worth while.

A dollar goes from hand to hand
And my girl goes from man to man

Her eyes were blue her lips were red
Her hair was curly but not on her head

Gonna tie her up in a 'tater sack,
She'll be true to me 'till I get back

So roust 'er up be quick I say,
An' make yer port an' take yer pay.
