Robby came close, but the words in the Digital Tradition (see Joe's link above) are what I've heard. One little detail--though I've never seen "official" printed lyrics, I was told by an Irish lady that I met here in the U.S. that it's "green and lovely vales of Killashandra". This is what I sing, as it makes more sense to me to describe a vale (little valley) as green and lovely than to depict a lane that way.
