My daughter went to dance school from pre-kindergarten through 8th grade....taking ballet, tap, modern and jazz.
We parents never saw the recital dances until the night of recital. However, if any of the kids at my daughter's dance school had danced like this....the parents would have been storming the stage! and not enrolling their kids in the school anymore. She hasn't been in dance school in over 15 years, but Madonna was doing some pretty risque stuff back then, and the kids weren't dressing - or gyrating around - like Madonna.
Flame's daughter is very active in dance school, recitals, and competition dancing. I know she's older...freshman in HS, maybe? I would be interested in hearing Flame's comments on this and what the parents at her daughter's school have said about this video as I'm sure if they have not seen it, they have at a minimum, heard about it.
