This is a more manageable text IMO; it's the same as Harry Cox's plus some verses (From Frank Purslow's Marrowbones)

THE CAPTAIN'S APPRENTICE
Hammond D. 593 . Mrs. Sartin, Carscombe , Dorset. July, 1906.
With additional text from D.547. George House, Beaminster, Dorset. June, 1906.

A boy to me was bound apprentice,
Because his parents they were poor,
I took him from St. James's workhouse,
All for to sail on the Spanish shore.

This boy one day he did offend me,
Nothing to him then did I say,
But straightway to my yard-arm I dragged him,
And I kept him there till the very next day.

His hands and feet they hung towards me ,
His arms and legs hung down likewise,
And with my tarry, tarry rope I killed him,
Because I would not hear his cries.

And then my men they did reject me ,
Because that I had done such wrong,
And in my cabin they close confined me,
And bound me down in irons strong.

To London town they then did bring me,
And here lay I condemned to die,
If I had by my men been ruled,
I might have saved the poor boy's life and mine.

You captains bold that sail down the ocean ,
That have got servants to wait on thee ,
I pray you never, never ill-use them,
For you plainly see 'twas the death of me.
