In this video Saas and Bahu, (As Friends) dancing in a marriage on “Saat Samunder Paar” song. It’s look some funny but the dance was awesome. This video is a similar video of another most viral video on YouTube where a lady dancing on same song.
This is another video with same song, may be Cadbury ad team got some idea form here.
