I discovered this song from the singing of William Pint and Felicia Dale, and recorded my version of it. From William, I found that Hearts of gold is, indeed, a traditional song, and as William said," we heard Hearts of Gold from our friend, the scholar/musician Stuart M. Frank of Massachusetts. He recorded it on a LP called Songs of Sea and Shore on the Folkways label back in the late 70s."
As such, I think it deserves inclusion in the DT.

Here it is. I play it in F

HEARTS OF GOLD
(traditional)

It was the plowing of the raging seas
Was always my delight
While those loving old landlubbers
No dangers do they know
Not like we long Jack Hearts of Gold
Who plow the ocean through
Not like we long Jack Hearts of Gold
Who plow the ocean through

They are always with the pretty girls
A setting them fine treats
And filling of their pretty heads
With the work they've done in a corn field
But the cutting of the grass and weeds
It's all that they can do
While we long Jack Hearts of Gold
Plough the ocean through

And when the sun it does go down
They must lay aside their plow
And their work they can no longer stand
It's homeward they must go
And they take their suppers with content
And into bed they crawl
While we long Jack Hearts of Gold
Stand many the bitter squall

The seas they run full mountains high
Which toss us up and down
We are in the midst of danger boys,
For fear our ship might found
Oh, but never be down hearted boys
We'll see our girls again
In spite of all our enemies
We will plow the raging main

We will sing to every port of land
Which every yet was known
We will bring back gold and silver boys
When we return to home
And we'll make our courtships flourish Boys
when we arrive on shore
And when our money is all gone
We'll plow the seas for more

So, come all you pretty damsels
If the truth you only knew
Of the dangers of the raging main
From labors unto you
You would have more contempt for them
Than ever yet was known
You would hate those loving landlubbers
Who always stay at home

If anyone is interested, my version can be reached here.

I would be curious to know any further history and origin info for the song.
