I'm not having much luck in tracking down the lyrics or history of an unaccompanied Irish song that's caught me.

It is an English translation - 1st verse goes something like

O far away from Erin's home some other brave sons roam
Across the broad Atlantic 3000 miles from home
No matter where they chance to stray they'll love each glen and vale
Where there Shannon's purple tide rose free through green robed Innisfail

The (long) story also has reference to Larkin and O'Brien and a cold Manchester jail
Thanks (in anticipation!!)
