A bit late here.... back to "The Time I've lost in Wooing" - I found the music in Songs of Ireland, Boosey & Co. book circa 1877 - Says the Air is "Pease Upon a Trencher..."
Funny, I just had someone write me about "Avenging and Bright" by Moore - which I'm working on... I just did a short bio of him on my pages because I've got a bunch of his music and didn't find any great links. Now I have TWO tunes to put up.
