I've merged the two threads, to keep all of the responses together.

In case you want to see the irish song which uses the same tune (which I've always found beautiful), here is one version (as noted already, there are variations), with a translation:

Maidin moch do ghabhas amach,
ar bhruach Locha Léin,
an Samhradh ‘teacht ‘s an chraobh len’ ais,
is lonrach té ón ngréin,
Ar thaisteal dom trí bhailte poirt
is bánta mine réidhe,
cé a gheobhainn le m’ais ach an chúileann deas,
le fainne geal an lae.

Ní raibh bróg ná stoca, caidhp ná clóc
ar mo stóirín óg ón spéir,
ach folt fionn órga síos go troigh,
ag fás go barr an fhéir.
Bhí calán crúite aici ina glaic,
‘s ar dhrúcht ba dheas a scéimh,
do rug barr gean ar Bhéineas deas,
le fáinne geal an lae.

Do shuigh an bhrídeog síos le m’ais,
ar bhinse glas den fhéar.
Ag magadh léi, bhíos dá maíomh go pras,
mar mhnaoi nach scarfainn léi,
‘s é dúirt sí liomsa, “Imigh uaim,
is scaoil mé ar siúl a réic.”
Sin iad aneas na soilse ag teacht,
le fainne geal an lae.

Translation:

One morning early I went out,
on the shore of Lough Lein.
the summer coming and the trees coming back,
and warm brilliance from the sun.
As I wandered through townlands
and level ripe pastures,
who should I find by my side but a fair maiden,
at the dawning of the day.

There was neither shoe nor stocking, cape nor cloak,
on my young darling from the sky,
but golden blonde tresses down to [her] feet,
growing to the top of the grass.
In her hands she had a milking pail,
and in the dew she looked so fair,
excelling even fine Venus,
at the dawning of the day.

The young maiden sat by my side,
on the green bench of the grass.
Teasing her, I pretended to claim
that I’d never part with her as my wife,
and she said to me: “Go away from me.
and leave me free to go roving.
There are the lights coming from the west,
with the dawning of the day."
