All who go onto SCD receive a very large payout for doing so. So, I do not feel sorry for any of them. All, also say, that it is a really great experience and I am sure that it is.
Okay some of them really cannot dance, and will probably never be able to do so. Not that it matters. They have a great time, they wear wonderful costumes, they earn lots of cash, and they entertain very many people.
Personally, I find the sameness very boring now Loved it many years ago, but cannot really take on such a long time each Saturday evening. But I know I am in a minority and whilst it gets such good ratings, would not want it discontinued.
