Recently the team of 'PK' was in Delhi for the first song launch of of the film and the team that had worked on the song was present at the event, except Sanjay Dutt. The song is really special for director Rajkumar 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.

We were told that the ace director, who shares a very special bond with Sanjay Dutt, missed the actor a lot at the launch. That's because, he felt that Dutt was a major part of the song and also because it was the last leg that Sanjay shot for. Confirming the news Hirani added, "I really missed Sanju on the launch. Its my first film where he is not standing with me on the dias."

'PK' stars Aamir Khan, Sanjay Dutt, Anushka Sharma and Sushant Singh Rajput and is set to release on 19th December.
