Amitabh Bachchan has lent his voice for a song titled Badumba in his upcoming film 102 Not Out. The veteran actor tweeted a photo from the dance rehearsal of the film.

Amitabh also wrote on his blog about the song. "One could sit inside the portals of a studio for hours just jamming and having the time of your life, those moments are special and precious. But with that comes the fear of the shooting of it and the apprehensions of performing it. Never a dull moment in our lives!" he wrote.

The film also stars veteran actor Rishi Kapoor. Amitabh's character will be seen as a 102-year-old father to a 75-year-old character of Rishi in the film, directed by Umesh Shukla. 

Billed as a most unusual father-and-son love story, the film is based on playwright Saumya Joshi's well-known Gujarati play by the same name. The film is scheduled for release on May 4.
