My 18 month old son, Darby, passed away a little over a month ago. I used to sing Danny Boy to him every night at bedtime. Darby was always so full of life and energy and that was the only time he really calmed down was when I sang. So, I had Danny Boy, sung by Johnny Cash played at his funeral. It was very beautiful.
Another song that Darby and his cousin, Lilly, loved was "When You Come Back Down" by Nickel creek. Another very emotional song we played.
