Hmmmmmm...Arjun you may be on to something...can anyone give some clarity as the the type of dance and the gender of the dancers? The comment wall for YouTube says that this is an Orissian dance
"Actually, this is Gotipua, which is a form of Odissi taught only to BOYS. It's a form of traditional Indian classical dance that actually survived throughout the times when the Mahari tradition (temple dancers) had died out almost completely. It it through this tradition that present day Odissi was revived, reconstructed, and codified. I can't comment on the living conditions of these children, but this isn't just a bunch of cheap tricks for show."
