Bollywood star Abhishek Bachchan is gearing up for his first world tour, saying he is looking forward to interacting with live audiences as this is more electric than just acting.

'The difference between acting in films and stage shows is that you interact with live audiences and the experience is more electric. You get immediate reactions, ' Abhishek, who is vigorously rehearsing for the tour, told.

Titled 'The Unforgettable', the tour kicks off from Toronto July 18 and will have Amitabh Bachchan, Aishwarya Rai, Riteish Deshmukh and Preity Zinta as its permanent members.

'We are also going to have a number of big stars like Shilpa Shetty, Akshay Kumar and Madhuri Dixit joining us. In the first leg of the tour (July-August), we will be in North America and Europe, ' Abhishek said.

'Hopefully, it will be very entertaining and we will try and ensure as much entertainment as possible like crowd interactions, dialogues and, of course, lot of dances, ' he said of the format of the shows during the tour.

'We have decided on the performances and songs. The rehearsals have already started because we are about a month away from our departure, ' the actor added.

'We have been rehearsing for the past three weeks and will continue for the rest of this month and in July as well. We have extensive schedule for rehearsals as there are no retakes on stage. But thankfully, the people who are going with us on the tour have been on stage earlier, ' he said.

A couple of stars had backed out from the tour, but Abhishek said this hadn't increased the pressure on the core group.

'Not at all! We are happy with the star cast we have and are very confident about the shows, ' he maintained.

'This is mine and Riteish's first world tour. But the basic attitude is to be very well prepared. And you have to work hard to be as professional as possible on the stage, ' the actor said.
