Here's my transcription, using the lyrics from Greum, the corrections by Reinhard, and a few of my own.

ERIN'S GREEN ISLE
(George Millar)

I have wandered the pathways and byways of Erin’s green isle
Enthralled by her beauty encountered for mile after mile
From the port of Kinsale to the north coast of Antrim so wild
Where nature prevails and your heart it will soon be beguiled.

When the mountains and glens are ablaze with the colours of spring
When the wee birds are singing their songs how the valleys do ring
While building their nests in the bushes of hawthorn and broom
And the wild purple heather it covers the hillsides and blooms.

There are castles and towers, reminders of days that are gone
And you’ll still hear the legends and stories and the music lives on
And when I’m far away no matter where I chance to roam
I will always think fondly of the green rolling hills of my home.
(repeat first verse)
