/> Venue Select City Mall, Delhi. Date: Saturday 6 September. Time: Late Evening. A crowd of 12, 000 people mobbed jostled and cheered lustily as the band from the film Rock On comprising Farhan Akhtar, Arjun Rampal, Luke Kenny and Purab Kohli played the songs from the film on stage.

Farhan who was down with high fever on the day of the eponymous concert just can't believe how far the film's message and music have gone.

"This is absolutely crazy. And we got a first-hand feel of it on stage on Saturday in Delhi. Watching the audiences' spirit and enthusiasm I didn't mind going on stage when I was so unwell."

What happened? "For three days I had a throat infection. On Friday it got worse. On Saturday I woke up with a 102-degree temperature.

This sweet doctor came and gave lots of medicines and advised me not to go on the stage. But he understood I'd die if I didn't go on stage. It was unbelievable. They were 10-12, 000 people come to see us. I can't put the experience in words.

Purab even performed his 'I'll Survive' dance from the film.The kind of energy created by the audience....It's gone way beyond the film. They've seen the film and they came to the concert to give us back something. The film has definitely brought the spotlight on Indi-rock."

At the moment Farhan sings live on stage while his colleagues just mime the musical movements. "But now everybody is keen on going really live.

Arjun, Purab and Luke want to play their own stuff live. So basically we want to work towards being a live band and perform without Shankar-Ehsaan-Loy supporting us on stage. Purab has already bought his drum kits and is practising religiously.

Arjun is going to go back to Chandresh who taught him guitar and learn some more. And Luke is practising the keyboards. As for me I've always been passionate about singing."
