The second tune posted above is the standard one and you can probably find other abcs and sound files on the web as it is often played as an air.

Pádraigín Ní Uallacháin composed her own air for a set of lyrics from her area of south-east Ulster - and her sister Eithne composed another air for the same song: relevant recordings are A Stór is a Stóirin and an Dealg Óir from Pádraigín and Bridgid's Kiss from La Lugh (Eithne Ní Uallacháin & Gerry O'Connor). I'll post some more lyrics later.
