'Saans' is sung by famous singer Mohit Chauhan and Shreya Ghoshal. The lyrics of the song is written by Gulzar and music is composed by Oscar winner singer AR Rahman. The song has some great visuals.
Shahrukh Khan and Katrina Kaif launched the song on Tuesday in a very unique way. While Shahrukh was present at the event, Katrina joined her co-star via Skype, as she is busy shooting for Yash Raj's Dhoom 3 with Aamir Khan in Chicago. In the event, both Shahrukh and Katrina spoke about their experience while shooting Jab Tak Hai Jaan.
Jab Tak Hai Jaan also stars Anushka Sharma and is slated to release this Diwali on 13 November.
