I came to know that he wasn't feeling well at one concert, but I didn't know when it became a critical situation. Before the tour, he looked fine. I don't know what happened as far as his health is concerned. The last time I met him was in India, before he went to the US. Three weeks ago, I was in Italy. He was supposed to be in the same town in Rome. When that got cancelled, I got worried.

I used to [watch him] and wonder if I would ever get the chance to play with him. Once, in Scotland, he called me and said [we should] play together. I couldn’t believe it. Subsequently, we started playing together, and when we were on tour, each day spent with him on stage was a learning process.
