This is an "Unfinished Version" of the Irish ballad - "I'll Take You Home Again Kathleen."
Written by Thomas Paine Westendorf (1848-1923) for his wife, Jenny, who was born in Ireland. He was a very poor musician and they were living in America at the time, when he wrote this song. It became a "hit" in his day and they were able to use the money from the song's success to finally return to Ireland.
Live Performance and "improvisation on the original tune," sung á capella by Dorothea Fayne (Mezzo-Soprano). February 2008.
