The Song in question isn't the traditional song Waltzing Matilda, but Eroc Bogles amazing gallipoli war song, The Band Played Waltzing Matilda, I couldn't get through it first time I tried it. Another of his also had a similar effect,The Greenfields Of France, sometimes titled Willy McBride

Another song that got to me was Hank Williams, Mother's Day. And My fav song to perform, very old Irish Read ballad, The Spinning Wheel, oddly the lyrics are quite a cheerful song, but tune is so lilting and reminds me of my childhood in Ireland where I heard it sung first, with a harp backing, beautiful song
