Megastar Amitabh Bachchan has sung a few lines of a lullaby for the forthcoming film Thugs Of Hindostan. He says he was excited to sing it. Amitabh said the song tells the depth of the bond between his character Khudabaksh, mentor of Zafira, essayed by Fatima Sana Sheikh.

"The song tells you the depth of the bond that Zafira and Khudabaksh share. I was most excited to sing this lullaby because it is not everyday that you get to sing one," Amitabh said in a statement. The lullaby has been composed by the talented duo Ajay-Atul and Amitabh Bhattacharya has penned it.
