The great Irish ballad singer Christy Moore. I recommend going to Youtube and clicking on "The Early Years: 1969-81", the whole album is great.
My favorites:
The City of Chicago
Nancy Spain
The Little Musgrave
Finnegan's Ball ("six fine months I spent in Dub-a-lin, six fine months doin' nothin' at all..)
and especially The Boys of Mullabawn
The man can tell a story.
