The new campaign for the 15th season of Kaun Banega Crorepati has host Amitabh Bachchan render a lyrical narration set to music composed by musician duo Rohan–Vinayak. They have previously given music to Bachchan-starrers like Pink, Sarkar 3, and 102 Not Out.  Rohan said, “Our first thought behind making Mr Bachchan hum the theme tune was that both the host and tune are the identity of the show, and therefore, it only seemed right for us to bring them both together to invite the viewers to a new season.” Vinayak added, “Having worked with him before, we know that his voice has the power and allure to bring this country together.”
