Bunty Walia's musical concert The Incredibles, is in trouble.

Slated to be held in 18 cities across the US, West Indies and UK in May, has gotten Sonu Nigam angry making him pull out of the gig.

The singer is miffed that he is being packaged as part of a group of singers (including Asha Bhonsle, Kunal Ganjawala and Kailash Kher), instead of being promoted as the main attraction.

Nigam is also upset that the show is being projected as an Asha Bhonsle concert with him as an added bonus.

When Sonu threatened to pull out, a representative of one of the main sponsors called to say that if he backed out, the sponsors would withdraw as well.

Now that Nigam has made up his mind to step out, a close friend of his tells us that the singer is not acting difficult. He is simply demanding what was promised to him.

"At the time of signing the contract, Sonu was told that he would be the main attraction, while the other singers would be add-ons. This may seem surprising because Ashaji is also part of the show, but the fact is that Rocky (the organiser) wanted to ride on Sonu's successful US concerts last year. The public there is anxiously waiting for him to come again."

Nigam was also paid more than Asha Bhonsle to do the concerts, because the organisers were confident of making good returns. Sonu's friend says, "Naturally, when Sonu learnt that Bunty was focusing more on Ashaji in his publicity campaign here in India, he felt cheated.

He considers Ashaji his mother, but that doesn't mean his brand should get diluted. Sonu didn't want to cheat his fans; he suspects Walia has scripted less of him in the concert than what was promised."

Nigam has admitted that he is not doing the show anymore. "Yes, I have opted out, but I don't want to dwell on the reasons for my decision. I will talk about this only at a later date," he says.

Meanwhile, Walia maintains, "Every form of publicity that I have done in India so far has been approved by the organiser Rocky. Beyond that, I don't want to say anything else."

Rocky, who is in London, says, "I am very stressed. I am flying down to Mumbai in the next two days. I have informed Sonu's manager Ben Thomas that I want to sort this out.

Sonu is nursing a misunderstanding. I am selling the show abroad as an Asha Bhonsle-Sonu Nigam Nite, and he had been told exactly that. Besides, I am publicising Sonu's name here very well, so he needn't be worried about that."
