I asked Michelle what she uses for her Poetry projects and she gave me the following ideas:

Sting: I'm So Happy I Can't Stop Crying (Irony, paradox, juxtaposition)
Tori Amos: Home on The Range (Allusion, compare/contrast with traditional interpretation)
Don Mclean: Bye Bye Miss American Pie (symbolism & allusion)
Be Good Tanyas: The Junkie Song (imagery, symbolism)

Lorenna McKennitt does a lot of poems as songs, even some Shakespeare, Yeats.

The one she uses a lot is the Jabberwocky by Lewis Carroll.. tons of onomatopoeia, alliteration, narrative, rhyme scheme. She has the students try to reinterpret it into their own words and has to be grammatically correct (i.e., nouns for nouns, adjectives for adjectives.. etc, etc)
