What song relates to the book The Pigman?

There isn't a song specifically *written about* Paul Zindel's *The Pigman*, but several songs thematically relate to aspects of the novel. Songs about friendship, growing up, facing mortality, and the complexities of teenage angst would all be relevant.

To suggest specific songs, we'd need to know what aspect of *The Pigman* you want to highlight. For example:

* For the friendship between John and Lorraine: Many songs about friendship would work. Something upbeat and slightly naive for their early bond, perhaps transitioning to something more reflective as their understanding of Mr. Pignati deepens.

* For Mr. Pignati's loneliness and eventual death: Songs dealing with loneliness, aging, and loss would be appropriate. Something melancholic and reflective would be a good fit.

* For the themes of teenage rebellion and responsibility: Songs dealing with growing up, making mistakes, and learning from them would connect well.

Without a more specific focus, it's impossible to recommend one definitive song. You'd need to consider the particular theme or emotional tone you want to capture from the book.
