For those interested, there is another interesting video posted here
Look for the post by Floskate on July 19. It's from the 1998 Challenge of Champions. It includes Katherine's EX number, but also an interview where she talks about her life as a Sr. Principal dancer starting at age 15. I bet things WERE pretty snarky in the ballet company when she was so young!! I love watching her skate but found the fluff piece interesting too.
