Now this is what we call a family affair; the Kapoors shaking a leg to a tune sung by Mika and older brother Daler Mehndi in ‘Besharam’.

The two older Kapoors play bumbling cops on the trail of Babli, the filmi goon played by Ranbir in the film and the trio unite for a special dance number, "Hand Uthake Nachche", where the two generations are pitted against each other in a jugalbandi.

The song composed by Lalit Pandit will have Daler Mehndi voicing Rishi while Ranbir's part will be sung by Mika.

A source close to the film's director Abhinav Kashyap said in an interview, "In the film Rishi and Neetu chase around Ranbir and the song will have a jugalbandi between the Kapoors reflecting the old v/s new theme."

Ranbir is currently in Sri lanka shooting for Kashyap's ‘Bombay Velvet’ and is expected to arrive back in Mumbai by the end of this month for the song's schedule.

"A set is being constructed at Film City and choreographer Bosco and Ceasar have been roped in for this song. Sunidhi Chauhan will be the voice of Neetu Kapoor and Abhinav is leaving no stone unturned for the big day. He has told his team to make sure that everything is in place before the Kapoors arrive to ensure a smooth shoot," the source added.

‘Besharam’ is slated to hit the big screens on 2nd October 2013.
