How to appreciate Sir Patrick Spencer's translation?

Patrick? Sir Spencer.

Dunflynn had a king,

Drinking wine as red as blood;

"Oh, where can I find a good sailor,

Sail my good boat? "

Sit on the king's right foot.

An old knight got up and said:

"Sir Patrick Spencer.

Is the top captain at sea. "

The king wrote an official letter,

And personally signed it;

Sent it to Sir Patrick Spencer,

He is walking on the beach.

Sir Patrick read the first line,

He smiled;

Sir Patrick read the second line,

Tears blurred my eyes.

"Oh, who did this?

Did this evil thing to me;

At this time of year,

Want me to go to sea. "

"Come on, come on, my guys,

Our good ship sails tomorrow morning. "

"No, oh no, my dear captain,

I'm afraid there will be a deadly storm. "

"I saw the new moon yesterday and last night.

Still hold the old moon in your arms;

So I was afraid, I shot, my dear captain,

We will suffer. "

Ah, our Scottish nobles are blameless,

They don't want to get their cork heels wet,

But the play is far from over,

Their hats are floating on the sea.

Ah, their women may have to sit,

I shook the fan in my hand for a long time,

Waiting for Sir Patrick Spencer.

Set sail for land.

Well, their women may have to stand,

Comb your hair with a gold comb for a long time,

Waiting for their own masters,

Because they will never see them again.

Halfway to Aberdeen, halfway,

At a depth of fifty fathoms,

Lie down, kind Sir Patrick Spencer,

At his feet is his Scottish aristocrat.
