Hi! Maybe it has to do with the shows that are Non-Union, and therefore the proper training is not in place. Maybe at the auditions, the girls sing wonderfully, but then without the care from the Union, things start to slip.
Or, prehaps sometimes, casting is done thru "connections"!
But, in the end, isn't great seeing kids perform, no matter what?!
Laura, your questions were valid and if you get slack from asking, I hope you realize you've done nothing wrong!
