Here are the lyrics as they appear in the sheet music. Only a few words are different (underlined); the most important thing is that the chorus is identified.

WILLIE'S ON THE DARK BLUE SEA
H. S. Thompson
Boston: Oliver Ditson, 1849.

1. My Willie's on the dark blue sea,
He's gone far o'er the main,
And many a weary day will pass
Ere he'll come back again.

CHORUS: Then blow gentle winds o'er the dark blue sea,
Bid the storm-king stay his hand,
And bring my Willie back to me,
To his own dear native land.

2. I love my Willie best of all,
He e'er was true to me,
But lonesome, dreary are the hours,
Since first he went to sea.

3. There's danger on the water now,
I hear the blond-bills cry;
And moaning voices seem to speak
From out the cloudy sky.

4. I see the vivid lightning's flash,
And hark! the thunders roar;
Oh Father, save my Willie from
The storm-king's mighty power.

5. And as she spoke the lightning ceased,
Hushed was the thunder's roar;
And Willie clasped her in his arms,
To roam the seas no more.

LAST CHORUS: Now blow gentle winds o'er the dark blue sea,
No more, we'll stay thy hand;
Since Willie's safe at home with me,
In his own dear native land.
