The Wiz... help please

Hi, I'm a teacher, directing The Wiz at my school next year. I'm finding the staging pretty difficult to get my head around. If you have produced The Wiz I would appreciate any advice of how to stage it, or any pictures would be great!! If you are in Sydney and have sets/costumes/props I would be very interested. Contact me on wrenjenni@hotmail.com Thanks! Jenni
