I'd like to see Madonna or Janet Jackson try to imitate this!!

It starts slow... The song and dance are entertaining... then suddenly is MORPHS into something you just won't believe.

In this classic footage from the movie "Broadway Rhythm" (1944), the Ross sisters, Aggie, Maggie and Elmira, sing and move in ways that don't look humanly possible. Yoga anyone? Movie buffs will recognize the tune as one of the background instrumentals from "The Godfather."

Where are they now? I could find nothing more about them on the internet. Does anyone know what else they did?
