Amitabh Bachchan and Vidya Balan are on a promotion spree. The duo recently paid a surprise visit to the students of Jamnabai Narsee School to promote their forthcoming venture Paa.

According to reliable sources, "Big B was seen dancing away to glory with the kids. The kids too, picked up his monkey steps and danced as if there was no tomorrow. Amitabh and Vidya gave a glimpse of the affection they share on-screen in Paa to the kids."

Abhishek Bachchan joined them later and played soccer with the kids.
