Not many know that Amitabh Bachchan too has a whacky sense of humour. And Big B showed it recently while releasing the music of Babul. He kept his speech short and crisp and ended it with a piece of advice to Bhushan Kumar. “The music is very good and the music director Aadesh Srivastava has done an outstanding job, and Bhushan please don’t convert the music into Bhajan track,” said Amitabh Bachchan amidst peals of laughter from everyone present.
