The biggest song ever!

Farah Khan's Om Shanti Om has been mostly under wraps for a while now, and we finally get to see some stills from a song sequence, a multistarrer to beat all multistarrers.

Evidently inspired by Manmohan Desai's star-studded John Jaani Janardhan in 1981's Naseeb, Farah decided to create her own mega song -- featuring over 29 top Bollywood stars!

While the stills here show off Sanjay Dutt, Saif Ali, Salman and Shah Rukh Khan grooving in the same frame, other stars showcased in the song are Kajol, Shilpa Shetty, Preity Zinta, Govinda, Priyanka Chopra, Rani Mukerji, Vidya Balan, Mithun Chakraborty, Rekha, Karisma Kapoor, Tabu, Lara Dutta, Malaika Arora, Urmila Matondkar, Shabana Azmi and Amrita Arora, among many others.

"Well, it's 20 years since that song in Naseeb, and we had to step up the star power," Farah described the song to a Mumbai daily.

The biggest song ever? With Sanju Baba and the three Khans proving to be just one scene in a mega event gaana, it sure looks like it!

Here is the evergreen video of John Jaani Janardhan which inspired Farah..
