As I have been to watch the shoot many times in Lonavala, the audience in the studio is quite a lousy one and they don't even clap when Sadman enters, they are forced and instructed to clap by the co-ordinators there.. and when the applaud isn't loud enough, they edit the video to add these recordings of loud cheer and applaud.. just like they do in all these award shows...
It's just fake background music, as usual.. to make it look like people in studio are enjoying it 😆
