It looks like Shah Rukh Khan is determined to leave no stone unturned to ensure his latest project Chennai Express works out just fine.And his latest brainwave is to get the much sought-after Honey Singh to compose a special item song for the film. A move that has apparently not gone down well with composers Vishal-Shekhar who are behind the rest of the songs in this eagerly-awaited film.Says a source close to Honey Singh, "He was very pleasantly surprised to get a call from Shah Rukh about a very special song." Says the singer, "I was very very surprised and happy to hear from Shah Rukh bhai. He said he wanted me to do a particular song for Chennai Express and told me to do what I could. I wrote and composed the song while I was in Mauritius. Both Shah Rukh bhai and I are huge Rajinikanth fans. This number is our tribute to him." About Vishal-Shekhar's disapproval of his presence in the Chennai Express soundtrack, Honey Singh shrugs, "What can I do? If Shah Rukh bhai asked me to do a song, I couldn't refuse. I am just doing my job to the best of my abilities. I can tell you this much. When the song comes out it will be a craze among not just Shah Rukh and my fans, but also among Rajini Sir's fans."
