There are a couple of Englished versions of "Dawning of the Day/ Fainne gael an lea" in the DT. (Which has nothing to do with the Furey song requested, but that's already been run to earth satisfactorily enough.) But it doesn't have this one, which James Healy (Second Book of Irish Ballads) declares to be the most singable, and which was recorded by Count John McCormack. It was written by Edward Walsh.

THE DAWNING OF THE DAY

At early morn I once had been
Where Lene's blue waters flow,
When summer bid the trees be green
The lamp of light to glow -
As on by bower and town and tower
And widespread fields I stray,
I met a maid in the greenwood shade
By the dawning of the day.

Her feet and beauteous head were bare
No mantle fair she wore,
But down her waist fell golden hair
That swept the tall grass o'er,
With milking pail she sought the vale
And bright her charms display
Outshining far the morning star
At the dawning of the day.

Beside me sat that maid divine
Where grassy banks outspread
"Oh let me call you ever mine,
Dear Maid" I sportive said.
"False man, for shame, why bring me blame!"
She cried and burst away
The sun's first light pursued her
At the dawning of the day.

(This is all happening by the banks of Lough Leane, one of the Lakes of Killarney. Where else?)
