SHAMITABH also stars RAANJHANAA actor Dhanush and Akshara Haasan.
Big B revealed about the same on a micro-blogging site. ''Balki and 'Shamitabh' meet... got to sing another song ..aarrrgghh !! am hopeless at this .. but guess will have to do it !,'' posted Bachchan.
While Bachchan sang 'Baatein Hawaa Hai' in CHEENI KUM and 'Mere Paa' in PAA, the name of the song in SHAMITABH isn't revealed yet.
However, singing is not new for Amitabh. He has sung various chartbusters in the past including 'Rang Barse' (SILSILA), 'Main Yahan Tu Wahan' (BAGHBAN), 'Mere Angne Main' (LAAWARIS), 'Bol Bachchan' (BOL BACHCHAN), 'Ekla Chalo Re' (KAHAANI) among many others.
