InOBU, I have heard, but have seen no documentation that Londonderry Air to which Danny Boy was written sometime around the turn of the 20^th century, is actually current to the 1790s.

I like the melody, Londonderry Air, but the Danny Boy lyric......well, a couple of shots of Jack Daniels (which I hate) would certainly be enough to wash the taste out of my mouth.

P.S. By the way, do any of you Irish/Celtic style musicians do any material from Thomas Moore (1779-1852)? He's one of my favorites. That's the closest I get to doing real Irish material. And it seems almost everybody has forgotten him.
