Bob Dylan - A Hard Rain's A-Gonna Fall
This would be good for teaching tenses. Or maybe just reviewing them in an end of term lesson. The way different tenses are used throughout. You could teach the concept of aspect with it: where's he standing as the narrrative progresses. And how his tense use depends on the question prompt at the start of each verse.
Here's the text of the lyrics.
EDIT: you could use a power point or wtf to look at a time line. Image of Bob, different points on the time line. Images to illustrate the lyrics.
