Here's a coincidence - this song seems to be making something of a comeback, since being recorded by an upcoming Irish singer named Daoiri Farrell - see link above, if it works.

I was in an Irish pub in Aberdeen 3 weeks ago, and a guy along the bar had asked to play this song over the house PA for some friends who were with him. I asked him if that was Daoiri Farrell singing, and he was genuinely surprised that someone in Aberdeen would recognise the song and the singer. I told him that the only other time I'd heard the song sung was by Andy Irvine, some 30 years earlier, in a concert in a hall some 200 yards up the road.
Daoiri Farrell is definitely someone to watch out for.
There are several sources of the lyrics if you just "Google" "Creggan White Hare" - I'd suggest those on Andy Irvine's website might be the most reliable on the internet.
