I think the Michael Jackson song, “I’m Starting with the Man in the Mirror,” would be great. Atticus raises his children to do the right thing and consider the feelings and needs of others. So he puts the burden of correct choices on them. Society only changes through the change of individuals.
To take a slightly different turn in the theme song topic, how about "Wind Beneath My Wings," by Bette Midler? Considering other themes besides prejudice and tolerance, I thought that the hidden courage of both Arthur Radley and Tom Robinson would be a perfect fit for this song. I listened to it again, imagining an adult Scout singing it. It fits perfectly! There are no better characters who were "cold there" in the "shadow" than Arthur and Tom! Quiet courage: something to be both lauded and applauded! : )
Strangely enough, Elvis's "In the Ghetto" would work well for describing the lives lived by the Ewell children, and John Mayer's "Father's Be Kind to Your Daughters" works well for not only how Bob Ewell should have treatedMayella (which would have then prevented Tom Robinson's fate) and also connects to how Atticus is trying to raise Scout.
"Where Is the Love?" by the Black-Eyed Peas also works well because it discusses what children are learning from their environment, different types of prejudice and hate, and even the government's involvement in spreading problems.
What about "Waiting on the World to Change" by John Mayer. I think this describes the townspeople of Maycomb in the sense that they are waiting for the world to change, but are not really participating in the fight for justice in the trial. They want Atticus to do all the fighting for them and just assume that someone else will answer the call.
What a fun question!
Here are a few suggestions:
"Pasttime Paradise" Stevie Wonder - Deals with ideas of racism and prejudice and how this things should and will change.
"A Change is Gonna Come" Sam Cooke - A change, particularly in race relations, is going to come.
"People Get Ready" - The Impressions (written by Curtis Mayfield) - Written during the Civil Rights movement, obvious themes of race and prejudice
"Time of Your Life" Green Day- Song about growing up, particularly the darker aspects of it.
"Ain't No Reason" by Brett Dennen is concerned with themes of racism and prejudice. It calls for the sort of social change that "To Kill a Mockingbird" represents.
How about "Carefully Taught" from the musical South Pacific? The lyrics talk about how prejudice is not born in people, but is taught to them by their elders. "You've got to be taught, before it's too late. Before you are 6, or 7, or 8. To hate all the people your relatives hate..."
"Southern Man" by Neil Young is another possibility.
What an interesting question! I haven't really thought of this before, but it definitely does make you think in a different way than normal. I would definitely have to say that a song I think would fit would be Hurricane by MS MR. The song describes an individual who doesn't know how to interpret the thoughts in her head, and how to act upon them, and I think this fits well because of all the characters that are either acting upon their thoughts or not, and waiting to see the outcome of those decisions.
I would choose the slow melody of "Turn the Page" by Bob Seger, because it seems like many of the characters are on a road leading somewhere but only a few actually arrive.
