An old book printed in Dublin in 1900 includes Irish words to a song the editor calls "The Foggy Dew" ("An Drúcht Cheothach"). Can anyone translate the Irish headnote for me? (I've had to type the dotted consonants as followed by an "h").

"Sean fhonn fíos áluinn agus fíos Eireannach an fonn atá ris an abhrán so; acht fasaios! Tá na sean fhocail caillte go deo. Tá abhrán gráidh deunta dhe le file éigin do chuir focail beurla ris."

Part of its seems to say that the original words to the tune are lost, but I'd like to know more!
