The last shot of Farah Khan's lavish mega-star song for Om Shanti Om is being canned with Preity Zinta, This over seven long days song features 29 other actors (excluding Shah Rukh Khan)!

Talking about the song, Farah says, "It's the title track of Om Shanti Om and involves a scene where superstar Om Kapoor (SRK) has won an award and throws a party attended by many members of the film industry.

OSO is based on the film industry and spans two eras. Shah Rukh, Saif, Salman and Sanjay will be seen together on screen for the very first time. They get up on a bar, take off their jackets and dance and all of them look like rockstars!"

Farah says, "As a child, always wanted to do something like John Johny Janardhan from Naseeb in my film. It had many big stars of that time featuring in it, so I wanted to top that song. A month ago, Shah Rukh and I started approaching stars and they were so sweet.

We personally met each one of them and they immediately agreed. Jeetuji told us to give him just one hour's notice, while Mithun flew in just a day before the shoot from Hyderabad. If some stars couldn't do the shoot, it was either because they were out of the country or didn't have dates."

Saif, Salman and Sanjay Dutt had packed up for the day but they waited for Dharmendra to arrive on the set and shoot his act. When he did eventually, the three boys too leapt into the frame and started dancing !

Jeetendra and his son Tusshar are coming together on screen the first time. So when Tusshar came on the sets, he told Farah that he was shy of dancing in front of his father, who is such a good dancer!

But the girls were better behaved. After Tabu and Urmila's act got over, they stayed back to cheer Lolo as she was dancing again after a really long time.

The only star who insisted on rehearsals, was Rekha.
