July 19th, 2008 . Five years ago, when he had no clue that he would one day marry her, Abhishek Bachchan had made a promise to Aishwarya Rai .

It happened during the making of their film Kuch Na Kaho in 2003 when Ash was headed for a world tour and tipped the organizers of the shows to ask Abhishek to be a part of the tour. Abhishek turned down the offer because he had no dates to spare. Since then Ash has been taunting him for that. But Abhi made a promise to her that one day he would definitely accompany her on a world tour.

Years passed and their lives turned out such that they ended up falling in love and getting married. Now, what did not materialize five years ago is finally going to happen.

For, Abhishek and Ash are headed to the ‘Unforgettable’ tour that will travel to Canada, the US and the UK. This is the couple’s first tour together. They, along with Pa Amitabh Bachchan , are at the helm of the tour.

The tour begins with a concert in Toronto on Friday.

Apart from the Bachchans, the tour features Preity Zinta , Ritesh Deshmukh and music composer duo Vishal-Shekhar .
Other Bollywood stars like Madhuri Dixit , Akshay Kumar and Shilpa Shetty would join the troupe on different legs of the tour.

Abhishek Bachchan, ‘Pa’ Amitabh, Preity Zinta and Riteish Deshmukh are the other members of the star-studded line up which will tour Trinidad, USA, London and Holland on the first leg of the show.

Akshay Kumar will be the surprise star guest in Toronto, with Madhuri Dixit stepping onto the stage in the US and Shilpa Shetty gyrating in London. While thousands are expected at these shows, Bachchan senior recollects the early 70s when he and Jaya Bachchan first went abroad for shows.

There were only five people in the audience for the show in Southall, London while at the next venue they were asked to drive around in the hope that some more people would arrive.

Cut to today, where the top tickets for London are priced at £157 (about Rs 12,500).
