It's not the north or south or the east or the west or Black or white or brown or yellow or red or Protestant or Catholic or Jewish or Muslim or whatever the case might be.

We're brothers and sisters whether we want to be or not," Brooks said.There is a display on Brooks' life inside the Kansas City Museum this month.
