Why are these people laughing at Christians? Oh yea...it's open season on Christians. The way Americans disrespect Christ and the church and yet bring more "honor and light" to non-Christian entities is nothing short of anti-Christ.
If you listen to the original studio version, it's a higher key. They took it down because he is obviously having vocal problems. Obviously. And Suzanne Vega is the woman. She's there because the little "dih-dih-dih" part is from her great 80s album "Solitude Standing". You should listen to it. It sounds WAY better than this performance.
