I found this first with Google Books, and then consulted an actual print copy at a local university. It's in The Dublin Magazine, edited by Seumas O'Sullivan, v. 27-28, 1952-3, page 6. [Oops! I forgot to write down exactly which issue I found this in; but it's a quarterly periodical, so there are only 8 possibilities.]

WORDS FOR OLD AIRS
By Padraic Fallon

I dedicate these songs to Mrs Costello of Tuam, who made that most interesting collection of Irish Folk Songs known as "Amhrain Muighe Sheola".


THE PRETTY GIRLS OF LOUGHREA
Amhrain Muighe Sheola No. 22.

My heart-strings make me music
If I but think of you;
And if you call me, darling,
I'll wear a feathered shoe,
And swim the Suir and Slaney
And the Shannon any day
To talk with you, my dear one,
And walk you round Loughrea.

Did I own all Portumna
And the markets of Athlone,
Or the wharfs and the money
That belong to Limerick town
I would part them to your people
O if you'd let me presume
To look upon you one long day
And be your squire in Tuam.

O Rose-leafed maid, it's easy
To blame the wastrel now,
But who was ever able
To harrow with a plough;
Not reared was I to labour
Or to watch the season's way,
But gambling, sport and pleasure
Lost me my own Loughrea.

In her grey house by the water
My love is dwelling still,
The moon's one only daughter,
O Lamp upon the Hill;
She'll braid her hair at evening
And those who walk the way
They think it's the moon that's rising
On the grey lake of Loughrea.

Last night abroad in London
I spent my only crown;
I toasted my own one
And after cried tears down;
I walked the lamps till morning
And I heard your harkaway;
I wished I was the red fox
That you hunted round Loughrea.

No Lent will last out Easter
And after, summer comes;
And fasting is feasting
When the sloe-bush buds and blooms;
The Queen of Hearts is lonely,
But the Joker's still to play;
I'll lead and I'll take her from you,
O Strong men of Loughrea.
