Jab Tak Hai Jaan is Yash Chopra's last film as a director. After eight years, Shahrukh Khan and Yash Chopra have teamed up again for Jab Tak Hai Jaan. While the first trailer of the movie created a stir with its beautiful poetry, the first song 'Challa' will impress you with its mesmerising lyrics and locations.
In 'Challa' song, Shahrukh Khan is roaming in the streets of London and he suddenly bumps into Katrina Kaif for the first time. Talking about this song Shahrukh Khan posted on Twitter, "Challa will be out on the Oct 1 (Monday). Looking forward to it, haven't seen it since we finished shooting it."
The song is sung by famous Sufi singer Rabbi Shergil (Bhulla Ki Jaane fame). 'Challa' song too has a Sufi touch in it. The music of Jab Tak Hai Jaan is composed by Oscar winner AR Rahman.
