Here's another version, substantially different both in words and tune. From Norfolk.

EDDYSTONE LIGHT 2

My father was the keeper of the Eddystone Light
He married a mer-my-aid one night!
Out of this match came children three
Two was fishes and the other was me.

CHO:
Jolly stories, jolly told
When the wind blows bleak and the nights is co-old
No such life can be led on the shore
As is 'ad on the rocks by the ocean's ro-ahr!

When I was but a boyish chip
They put me in charge of the old light ship
I trimmed all the lamps, and I filled 'em with oil
And I played Seven Up according to 'oyle

CHO
Jolly stories, etc.

One night as I was a trimmin' of the glim
Singing a verse from the evenin' 'ymn
I see by the light of the binnacle lamp
My kind old father, lookin' jolly and damp
And a voice from the starboard shouted Ahoy!
And there was me grandmother, sittin' on a buoy.
(Meanin' a buoy for ships what syle
And not a boy what's a juvy-nyle myle!)

CHO
Jolly stories, etc.

From the singing of Wallace House, Folkways FP 823, 1952
