Who can do this ??
This film clip shows some of the astonishing contortions some people are able
to do, along with music.
In this classical choreography of the 1944 film "Broadway Rhythm", The Ross Sisters, Aggie, Maggie and Elmira, sing and move in a way that does not seem humanly possible.
During the first 45 seconds they sing. But what comes next is really impressive.
