Parsifal on stage in "De Munt"

The flyer you can see in my first post (18/06), was distributed in "De Munt" in June 2010. For the opera Parsifal, "De Munt" is looking for 200 extras. For me it would be a once in a lifetime opportunity to follow the creation process of an opera from close.
I have to think about it, since it will ask a lot of my time during the most busiest time of the year at work.
