Amitabh Bachchan, even at the age of 75, won’t let his health come in the way of his passion for work. The actor recently recorded a song for his upcoming release ‘102 Not Out’. Narrating his experience of what happened, Big B shares, “The world of music knows no boundaries and no rest, despite late hours and medical procedures. In ‘102 Not Out’, there is an additional song now; I mean how can production push a non-singer to these limits.” Amitabh Bachchan plays a 102-year-old father to a 75-year-old son, played by Rishi Kapoor. ‘102 Not Out’ is directed by Umesh Shukla and releases on May 4.
