Varsha, Roja was in the kids special in 2007. She did not win but the judges really liked her (she is really very humble and sweet). I guess because of that she also performed in one of the award shows.
I also saw another girl in DID from BW. They did not show her performing in DID but she was wearing a silver and black outfilt. She was also in one of those competitions in BW last year. She was from Ranchi and she has a gap in her front teeth.
These are the two contestants I noticed from BW because I do not watch BW anymore.
