Just read this thread and it brought so many songs to mind.Two modern songs spring instantly to mind -- "The Bravest" and "There were Roses".
"Fields of Athenry" (sung slowly - not the upbeat version) and "Carrickfergus" because a friend asked me to learn it and then died two weeks after hearing me sing it for the first time. (The two events were not related before anyone asks!!) I still sing "Carrickfergus" but struggle to get the last line out.
Great thread
