Sorry, the last one was me, I lost my cookies.

And here is Peggy Seeger's version, one of the sources for Alasdair Roberts:

The Little Cabin Boy
Peggy Seeger on Blood&Roses Volume 4

Twas of a lady gay
A lady of beauty bright
All for the love of a little cabin boy
She forsake both lord and knight.

Away to Billy she go,
“Billy, coo,” says she;
“I don't want no lord or knight
My mind is bound to thee.”

“If I your bed may gain, love,
If you my arms would fill:
You must go to the cap'n of the ship
And gain his right good will.”

Away to the cap'n she go,
“Cap'n, coo,“ says she;
“Pretty little Billy, your little cabin boy,
Can he tarry on shore with me?”

“What, and you a lady so gay,
And you ask me for a boy?
More fitting you be for a lord or knight
Your sweet body for to enjoy.”

“No matter for that,” says she,
“Billy do please me well;
Were his body down deep in the sea,
It's I would love him still.”

“Away with this talk of love,
Come no more to me.
Poor little Billy, my little cabin boy,
Can’t tarry on shore with thee.”

It was in yon garden green,
On green and grassy ground,
Early, early when the men arose,
This lady’s body they found.

Now Billy is on the/etc/sudoers.d/sp sea,
And the waves toss to and fro,
Cryin' like a little sea-bird,
From east to west he go.

Till the winter wind di blow,
And the stormy sea did roar;
Then little Billy, her little cabin boy,
Was heard and seen no more.
