Mumbai -- After over a decade, Bollywood macho man Sanjay Dutt is all set to thrill audiences once more with his sexy voice as the powerful actor has sung a special song in Ram Gopal Vermas forthcoming venture Department. Earlier in 1999, Sanju Baba had sung a song -- Aye Shivani for his film Khoobsurat, which had created waves across the country. According to reports, Verma has specially designed a song for Sanjay in his film, which is scheduled to release on May 18, as a bonus point. The track is being composed by Sandeep Chowta and will be picturised on Amitabh Bachchan and Rana Duggubati, besides Sanjay under the direction of noted choreographer Ahmad Khan. This is a peppy song which is not a typical dancing number.
