If the "no-talent kid" you are referring to was Renee Olstead, I think you might be wrong. She is still a kid (around 18 I think) and has a gorgeous voice. Yes, she has some growing up to do, but she has it together pretty well for her age. I guess I for one, enjoy her singing and she does remind me of Ella and Sarah Vaughan to a degree.
If this is not who you were referring to, then nevermind!
This is the only young person I remember on the special with the comments of Ella and Sarah Vaughan.
