It's become the norm rather than the exception to do favours for friends by doing cameos and item songs for free in their projects. Amitabh Bachchan returned Shah Rukh Khan's cheque after doing a cameo in his home production, Paheli. Now Abhishek is doing the same.
The Junior B recently shot for an item number for Apoorva Lakhia's Mission Istaanbul sans any compensation leaving Popcorn producer Sunil Shetty stunned!

Nobody Like You — that’s the title of the zingy song that Apoorva Lakhia will shoot for Mission Istanbul with Abhishek Bachchan on three consecutive nights from 21 June onwards.

Confirming the shooting of this belated song-and-dance, Lakhia says, “Abhishek has always gone out of his way for me. He had a cameo in my Ek Ajnabee and Shootout At Lokhandwala. In fact, I consider the Bachchans lucky for me. Right at the start of Mission Istanbul, I had asked Abhishek to do a song and dance for me. We were just waiting for him to get the time.”

The next few days will be extremely hectic for the makers of MISSION ISTAANBUL. Reason being, two separate songs will be filmed, almost simultaneously, on Abhishek Bachchan and Vivek Oberoi at different locations of Mumbai [Abhishek makes a special appearance in the movie]. That's one of the reasons why the release has been pushed ahead by two weeks.
