I've done it both ways (group and solo) with a simple three chord arpeggio backing. I first heard it in Maine a couple of years ago at camp where the chaplain had fallen in love with it. My first reaction was that it was morbid, but a little listening convinced me it was about life's journey, not just the end. The tune is lovely. I don't know how an audience would take to it but I have little trouble getting friends to pick it up.
