For anyone who chooses to read it for themselves, the letter from the creators mentioned in the article can be found in full on the Hairspray page on the MTI site, under the "billing" tab.
http://www.mtishows.com/show_detail.asp?showid=000297 The creators DO acknowledge that in some cases, amateur companies may not be able to find a suitable ethnic make-up. Let's be honest, sometimes it is sometimes a group such as those that could benefit most from the themes and lessons of Hairspray.
To be frank, this is a group of children performing in a strip mall in Plano, TX. If anything should be taken from this article is that the director and choreographer BOTH seemed to resent and be embarrassed at working on the show with just white kids, justified or not. rather than being proud of what the kids were doing 9well or not), or finding any number of creative ways to address the racial disparity and spin it to somehow work to their advantage*, they threw the kids under the bus and said, "Nope, not my fault we no black people and I am ashamed". They couldn't even really find a way to say that it is a shame that they weren't able to draw black children into the show and keep them there..
* they could have stated that having white kids worked to the idea that white kids and blacks kids, as Tracy says, aren't so different. They could have said that, like Tracy, you the audience member were not seeing the racial differences. They could have said "This show has a fantastic message and great music. Come out, see it. It is a shame that we weren't able to recruit black kids for the show and we want to reach out and involve minority children in this program so that we can do this show again in the future with the racial divide intact".. any number of things. SHAME.
