Here's another sentimental song about Donegal, also credited to "McBride", wonder if it's the same person. Transcribed from a 1969 recording by John Kerr, so maybe some minor mistakes in lyrics, tho not with the place names.

AT HOME IN DONEGAL

Though o'er the sea, tonight I be,
In thoughts, I'm still at home,
I roam the hills, where singing rills,
Cascade in flecks of foam,
From azure sky, away up high,
The skylarks freely fall,
My happy dream, by lough and stream,
At home in Donegal.

I love to think of far days,
When we were gay and young,
And of the dances that we danced,
The sweet songs that we sung,
The Aran men, the kitchen, where,
We gathered, big and small,
And my heart's desire, a grand turf fire,
At home in Donegal.

Down memory's way, I oft do stray,
To beautiful Mulroy,
Where wavelets on the shingle play,
That God's own sons enjoy,
Again I'll stand, on Downings' Strand,
When evening shadows fall,
And sunset on Sheephaven Bay,
At home in Donegal.

Oh! Grá mo chroí, I soon will see,
Far famed Glencolmkille,
Through Glenties, Rosses and Gweedore,
I'll ramble on at will,
Falcarragh, Creeslough, Carrigart,
I long to see them all,
My hand they'll take, and warmly shake,
At home in Donegal.
(Note: gra mo chroí – "gra mo cree", literally, "love of my heart")

My exile past, and home at last,
What thoughts of joy I feel,
In my own town, I'll settle down,
In lovely Carrowkeel,
I'll walk once more, that golden shore,
In scenes that e'er enthrall,
For life is joy, around Mulroy,
At home in Donegal.
(Note: Carrowkeel is pronounced, "Kerrykeel").
