Not sure why the thread title was amended (Joe?), this discussion is not about the Sliabh Luachra variant but hte one that came with this comment (on thesession.org):

'Maybe it’s because I learn’t it from O’Neill’s but I much prefer the 2 part version notated there - it was also recorded by the Northern trad group (fogotten their name but Pat McCabe played piano box with them) back in the early eighties as a two part jig and sounded brilliant. The setting is as follows:-

d|edB GAB|DED GAB|DED cBA|BGE E2d|
edB GAB|DED GAB|AGE cBA|BGG G2 :||
d|Bdd def|gfe dBG|A2A AGA|BGE E2d|Bdd def|gfe dBG|AGE cBA|BGG G2 :||

It also sounds great played slow with emphasis on the E minor bit at the end of the fourth bar!'
