Aha, got the beginning, if not the title. And I've BEEN to all these places on my Clancy Brothers Tour of Ireland!

One evening of late out of Bandon I strayed
And out for Clonikilty I was making me way
At Ballinascarthy some time I delayed
For to whet me ould whistle with porter (There is a pub there called the whistle, fyi)

- anybody can tell me the title and get me off this block will earn my gratitude... thanks! Also, I make no claims to spelling these town names properly, my apologies.
