I'd keep "Poor Jud's Daid" from Oklahoma in my back pocket if things get too sombre but I wonder if they're too young. Its hard to teach about expressing loss when so many families don't discuss it or your audience might be too young to have faced it.

If they've seen Lord of the Rings "Fellowship of the Rings" you might discuss the eligies being sung by the elves for Gandalf and Sam's poem.
