Info on the song:

From the Folkways liner notes for And So Will We Yet

THE BERGEN
(Jez Lowe)
©1986, Fellsongs
Side 2, Band 4.
Jake Walton and Jez Lowe recorded this on their Fellside album, Two a Rue, from which I quote:
"The Bergen was a ship from Finland that was wrecked on the Northeast coast of England a hundred years ago. The song was written when Jez came across the graves of its unnamed crew in his local
churchyard." [GB]
Ann: lead vocal and harp; Ed: 6-string guitar; Gordon: 'cellamba.

Sleep, why do you wake me with these dreams you bring?
    Dreams came to me where I lay.
Deep the melody the wild waves sing
    My love is far, far away.

CHORUS
Oh, pity the hearts the wild waves part;
My love sails the bonny barque, the Bergen.

(Similarly:)

They heap their nets upon the decks by the light;
Then creep out, gentle at the dead of night.

They reap their harvest from the cold night sea;
It leaps with herring in the hold for me.

Steep waves ride above his cold,fair head;
Keep him safe to lie here in my bed.

It weeps with rain tonight where my love lies;
Oh, sweep the foreign sand from out of his eyes

To be honest with you, the tune doesn't sound like a hymn to me, or at the very least a traditional hymn, but that doesn't mean there couldn't be one.
