He said the concept is about a non-dancer learning different forms of dance and his/her transformation to a dancer. But the name is "dancing with the stars" and they have been taking professional as well as non-professional but trained dancers since season 1...
Even this season is flooded with celebs trained in one form of dance or the other- exceptions being Sid, Shaan, Srikant, Suresh and Mantra. KJo meant to say it was brave of Sid to take part in the show knowing the fact that he would b mostly competing with others who have some sorta dancing background.😊
