Hi Threelegsoman

Believe me - I know what Irish sounds like! ;>)> To read "mhaith" into what the Clancys sing on that recording is stretching things a little, at least. Both the long "aw" sound and the fade at the end are at odds with the normal pronunciation of the word.

To be clear, I'm not saying that "oíche mhaith" wasn't the origin (though I doubt it) - but that the Clancys weren't singing it.

Oíche mhaith!
