With regard to the extensive repertoire of songs, of all kinds, listed above, well, "Genevieve", "My Grandfather's Clock", "Hanging on the old barbed wire", "If those lips could only speak", "I'll walk beside you", "Mother Machree", "Irish Molly-O", "Miner's dream of home", "Old Kentucky Home", "Old Rustic Bridge", "Silver threads among the gold", "There's a long, long trail a-winding", "Two lovely Black Eyes", "The wearing of the Green", "when the fields are white with daisies", "Woodman, spare that tree", ?"While Shepherds watched [their flocks by night]?", were certainly "modern stuff" not that long ago, and most of these are simply popular songs from the Music Halls; often a date of publication, author, composer and singers particularly associated with their performance can readily be found. Did the singer distinguish at all between these songs/that kind of song and those which had an earlier origin?
