I've never watched Trainspotting. I just know it's a very critically acclaimed film. In fact, I've never watched any of Danny's movies [means before he met him]. I just worked with him and felt the energy of what he is about initially before I do something. In a way, I think that's why we have discovered each other rather than replicate something else.

We didn't want to do that. It would have been a beautiful moment in the movie but it would have brought the movie down. So Danny's vision was perfect I think when he wanted it to be driven at the same time having this new emotion about this boy coming as a hallucination or like a déjà vu and as the future kid.

If a musician wants to blossom into a full-fledged person, it's not enough if he knows only classical music; nor it is enough if he's well-versed only in raagas and techniques. Instead, he should be a knowledgeable person interested in life and philosophy. In his personal life there should be, atleast in some corner of his heart, a tinge of lingering sorrow.

It's a very simple process. He [Danny Boyl] comes in the tube (subway) and then he sits with me for 3 hours every evening and then I work on something. Then later, if he likes something, I put it even more perfectly. I tweak stuff. So this happened for 3 or 4 weeks and the music was done.

In my case, dust has become gold: Today, I work with people I grew up admiring.

What is good is what it's going to lead to, like the song "Jai Ho." If good numbers are going to come in the future, it bodes well for a lot of things. But then, who's going to maintain that. That's the question. So far they could never lead to an Indian song, like a normal film song in this that they can relate to.

I've been doing music for many years and after a point what is the motivation that drives you to compose and to do stuff? I did this song for the U.N., a fighting for poverty anthem. That's when I realized that I could do a foundation. And when I started the foundation, it was basically to fight poverty and to help - that kind of stuff.
