How are you doing, Mumbai?" yelled Ranbir Kapoor soon after he emerged from under the dais in a well-rehearsed move.

The tormented soul Janardhan Jakhar that Ranbir plays in the movie tells the crowd that he is looking out for some feathered friends that flew away after their abode in the jungle was usurped by the city.

"Main un parindon ko dhoond raha hoon. Aap ne kahin dekha hai unhe? (I am looking out for those uprooted birds. Do you know where I can find them?)," Ranbir asked the audience, reflecting Janardhan's angst.

I have come here for A R Rahman," she says when asked if she finds Ranbir hot. "I love his music."

She doesn't seem to be particularly animated during Ranbir's performance, but springs to life when Rahman makes his entry on the stage. At just about 4 ft 5 inches, she cranes her neck to catch a glimpse of her icon from behind some 50-odd heads that block her view, moving to her left and right, and trying to push her way ahead.

Would you watch Rockstar to see Ranbir? "Not just him," says Adil who is accompanied by his middle-aged parents.

"Rockstar is also about super music." And are his parents Ranbir or Rahman fans? "Neither. They just love good music." He tries to get them to leave before the concert ends so as to avoid the crowds and also because "I have to report to office tomorrow at 5 am." A pragmatic fan, this.
