here's the one I know and it's VERY different from Art T's:

Oh where is my sailor boy,
Where is my sailor boy
He sleeps at the bottom of the deep blue sea
And he can't come back to me
I stand on the beach alone
And gaze at the misty blue
Deep sea as you hold him to your breast
Does he mention my name to you

Oh what does the deep sea say
What does the deep sea say
It moans, it groans, it splashes and it foams
And goes on its weary way

Oh please tell me deep blue sea
Is he sleeping peacefully
The winds on the foam are blowing icy cold
Will you keep him warm for me
If only my grieving soul
Some token or sign could find
If only the waves would tell me where he sleeps
I would leave this world behind

A beautiful rose one day
I placed on the brow of the wave
Saying waves, take it please, and let its petals fall
Upon his wat'ry grave
The driftwood I watched in vain
My rose never came back again
So waves take another message to my love
Saying I'll meet him above
