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.
