I just found this on youtube. I thought it might help you. My mom used to sing the chorus to us with a story she'd tell about the little boy trying to prevent his sister's death. But in her story, they both ended up happy in heaven together. I'm sorry about the loss of your grandfather. Perhaps he and my sweet mother are comparing notes now in heaven. :)
