The makers of Jab Tak Hai Jaan are out with their first music track ‘Challa’. Shahrukh Khan, the handsome hero in the film, is seen strumming the six-string, entertaining the passerbys, on the streets of London.

Its a Punjabi number, sung by Rabbi Shergill, written by Gulzar and composed by A R Rahman. Shahrukh is seen doing odd jobs like washing cars, vegetable vending, etc. The actor does look convincing with a guitar in his hand, singing away to glory. As the song comes to an end, our super sexy, romantic hero meets his heroine, the glam doll Katrina Kaif. She drops a coin, exchanging a brief glance and walks away.

Jab Tak Hai Jaan is Yash Chopra’s swan song. It’s slated to release on November 13. Directed by Yash Chopra, the film will sees Shahrukh Khan playing the role of an army officer named Samar. The movie also stars Katrina Kaif and Anushka Sharma.
