After getting Boman Irani to render the title song in "Home Delivery", music directors Vishal-Shekhar are now said to be working on another foot-tapping number, this time for their favourite maker Sanjay Gutpa.

And word is that the duo is set to record the pulsating number in the voice of their favourite star-singer Sanjay Dutt for his forthcoming project "Zinda."

"I didn't know the news was already out. Actually we wanted to spring a surprise on Sanjay Gupta. It is true we are planning to record another song in the voice of Dutt after tapping his voice in 'Kaante' and 'Musafir," said Vishal.

According to him, they are still working on the number that will be rendered in Dutt's voice. "But it will certainly be a very catchy number that will send the audience swinging to the beats."
