Kareena and Katrina may seem like odd allies. But Kareena was seen waltzing to the song 'Walking On Sunshine' by the 1980s' American rock group Katrina and The Waves in the first promotional clipping of Jab We Met.

It suited the mood of her ebullient and extroverted character to the hilt. But then suddenly Kareena was no longer walking on sunshine. The song vanished from all promotions for the film! What happened?

Director Imtiaz Ali reluctantly admits the song was pulled off. "It went perfectly with Kareena's character and the film's mood. In fact I didn't only want to use it in the first promo but all the promotional campaigns and also as part of the background music in my film."

Alas, filmmaker proposes, copyright disposes. Imtiaz Ali just couldn't track down the producers of the song 'Walking On Sunshine.' "The song was recorded in 1985. The band is now defunct. We couldn't source the song to its origin."

Rather than risk a sticky copyright-infringement situation, Imtiaz decided to pull the plug on the track. This latest incident of copyright consciousness in Bollywood is part of a larger campaign to acknowledge and legitimize all derived works in Hindi cinema, especially after the makers of Partner were accused of snitching Hitch without permission.
