I must be missing some hidden meaning in these wikipedia link/lyrics because what I'm getting from them is a song about a guy who broke out of prison for killing a guy who raped his sister when he was 20 and was in jail for 18 years.. I guess the point is he was gone from society for 18 years? Am I the only mid-30s person who doesn't feel like they're unhip?
