Megastar Amitabh Bachchan has proved his mettle in different fields from acting to hosting a TV show. He is known for his distinctive baritone. He has also sung numerous songs for his film. This time legendry actor surprised musical duo Vishal-Shekhar with his natural singing ability.

During the recording of the song 'O Re Saawariya' from his upcoming film 'Aladin', Bachchan came up with an alaap which was later added in the end of the song. Big B surprised everyone with his ability to sing alaap so well without any professional training.

Vishal says: "What impressed everyone all the more, was the fact that Mr Bachchan, who is not really professionally trained, was able to sing it so well. Singing an alaap is not easy and requires thorough practice. But Amitji did it wonderfully and that's really amazing."
