Mumbai: Actor Abhishek Bachchan has lent his voice for a promotional video of his upcoming flick `Dum Maro Dum, in which he will be seen essaying the role of a cop.
In Rohan Sippy`s earlier movie `Bluffmaster` Abhishek had sung `Right Here Right Now`, a hip hop number which became a huge hit. But, Dum Maro Dum`s `Thayn Thayn` is about Abhishek`s character ACP Kamat.
"The song is gritty, grungy. The last song they (Abhishek and Rohan) worked together on, `Right Here Right Now`, was a complete hip hop, cool video. `Thayn Thayn` is very different from `Right Here Right Now`. The song`s essence is ACP Kamat," sources said.
The song, composed by Pritam and choreographed by Rohan, also talks about corruption in the system.
