Agus rinne mise cleas ag Tigh Mhic Ui Dhomhnaill aréir
Is an tarna cleas ag teach an Ósta lena thaobh
Is an triú cleas ní bfhearr domh a chur le mo scéal
Is gur mhinicí domh bheith ag caitheamh an dúthracht mhaith léi

I did a trick in O Domhnall's house last night
And a second trick at the holstelry next door
I'd prefer not to add the third trick to my story
And I often spent a good (don't understand dúthracht ) with her

The rest of the song is at this thread
