Here's a link to a song I wrote a few years ago, when my wife's mother died, and I sang it when my brother died; and I always seem to sing it when someone I care about dies - Over the Edge of the World

And here's the first verse:

Now you've left us behind and you've gone on your way,
over the edge of the world.
You left without warning with so much to say.
Are you just round the corner, or far far away?
Well, goodbye, and I hope I might see you some day,
over the edge of the world.
