This song can be found on I-Tunes sung by Glen Curtin and it is called "Tonight is our last night together". My Mother is always singing this song and we have been searching for years for it. Finally found a version on I-Tunes, and the only difference is the first line in the song. The song says "Lastnight as I stood on a station platform", where as my Mum's version is "Lastnight as I stood on the Banks of the Boyne". The rest of the song is the same as the above versions. She is from Lahinch in Co Clare, Ireland. Hope this is helpful!
