and here's a clickable link for the recording on youtube

I wonder if you would consider Geaftaí Bhaile Bhuí as "bawdy"? (and by the way, I love the air and would like to have a different set of lyrics in Irish to sing to it, if anyone can suggest something suitable)

And there are lots of songs with erotic content, often quite subtle, which wouldn't be described as "bawdy".
