The song is really special for Rajukumar Hirani as he wanted to try something different and it has worked well for the film.
Also it was his idea that the characters in the song don the clothes of a bandwalla.
The ace director missed Sanjay Dutt a lot at the launch as he felt that he was a major part of the song and also because it was the last leg that Sanjay shot for.
P.K. stars Aamir Khan, Sanjay Dutt, Anushka Sharma and Sushant Singh Rajput and is set to release on 19th December.
Rajkumar Hirani comfirms the news and adds, "I really missed Sanju on the launch. Its my first film where he is not standing with me on the dias."
