Amitabh Bachchan has shared a rare black-and-white picture when he was rehearsing to sing his first song and Hrithik Roshan was witnessing the moment as a child.

Hrithik Roshan is the one who witnessed Amitabh Bachchan rehearsing to sing his first song, Mere Paas Aao Mere Doston, in his 1979 film Mr Natwarlal. Amitabh has shared a rare black-and-white decades-old picture from the day on Instagram.

Hrithik Roshan on the sets of Mr Natwarlal starring Amitabh Bachchan.

It shows Amitabh in a striped tee and bell-bottoms, rehearsing the song with the lyrics in his hand. Music director Rajesh Roshan is seen sitting in front of him as he observed his efforts. Two kids are seen comfortably sitting on chairs on the set and keenly watching the veteran actor. It's interesting to note expression on Hrithik's face as he looks on.

Sharing the image, Amitabh wrote, ".. the first song I sang for film .. ‘mere paas aao ..’ for Mr Natwarlal .. music rehearsal with Rajesh Roshan , Music Director .. AND .. all this being overseen by one ‘palti maar ke ‘ little one sitting on the bench ... a certain HRITHIK ROSHAN."

The picture received a lot of love from his fans in the comments section. A fan wrote, "I love how there were actual children during the recording of the song, so precious." Another said, "Haha look at HR's expression." One more commented, "The little boy is watching you in awe, the way the rest of us look at you now! @hrithik roshan too cute."
