As a newcomer still looking through old threads for anything of interest, I don't see that anyone posted the lyrics for Song of Glendun, so here it is:

Sure this is blessed Erin an' this the same glen
The gold is on the whinbush, the water sings again
The fairy thorn's in flower, an' what ails my heart then?
Flower o' the May, flower o' the May
What about the May-time an' he far away?

Summer loves the green glen, the white bird loves the sea
An' the wind must kiss the heather top, an' the red bell hides a bee
As the bee is dear to the honey flower, so one is dear to me
Flower o' the rose, flower o' the rose
A thorn pricked me one day, but nobody knows

The bracken up the brae-side has rusted in the air
Three birches lean together, so silver limbed and fair
Och! golden leaves are flying fast, but the scarlet roan is rare
Berry o' the roan, berry o' the roan
The wind sighs among the trees, but I sigh alone

I knit besdie the turf fire, and sin upon the wheel
Winter nights for thinking long, round runs the wheel
But he never knew, he never knew, that here for him I'd kneel
Sparkle o' the fire, sparkle o' the fire
Mother Mary, keep my love, an' send me my desire

(from Mary O'Hara's book "A Song for Ireland")
