This publicity vehicle is circling the park playing christian music. The man in the white suit is a "street preacher".
Benson is very superstitious. He comes from a voudoo influenced family. He is scared of the "Day of the Dead" holiday. He was told by his uncle when he was younger that the dead walk around on this day. He didn't want them to see him! Manu is just playing. Pray that the christian influence in his life will take away all his superstitions as he grows in the faith.
