/> It was meant to be a romantic summer song for Abbas Tyrewala's film to be shot with the director's wife Pakhi and John Abraham on various locations in London in the sizzling-hot climate of May.

Who was to know that the temperatures would dip dangerously and unexpectedly low to a shivering winter-condition in the middle of the famed English summer, thereby throwing the summer song into a state of confusion and panic.

Apparently the May climate in Lomdon became so cold that Pakhi, wearing thin summer dresses, almost passed out.

Recalling the harrowing experience Abbas says, "This was global warming in reverse. We had planned the romantic song months in advance for May to capture the soft summer light and shades in London. Pakhi's clothes had been designed accordingly."

Once the song started shooting the London weather grew alarmingly eccentric and began to act really strange. "No one had ever heard of such freezing conditions in summer. It was bizarre, " shivers Abbas in remembrance of the chilling experience.

Even more bizarre was Pakhi dressed in summer wear in the unexpected winter conditions.

Explains Abbas, "She had no choice. We had planned this as a summer song. She had to be dressed in backless dresses and noodle straps."

End-result ... Pakhi collapsed in the freezing cold.

Says Abbas, "In fact John who joined Pakhi in the song two days later told us it was too cold even for him although he was fully covered. We didn't listen. We had no choice."

The experience has taught Abbas that planning schedules according to the weather is no longer foolproof. "You could plan a summer shoot. And the weather conditions could turn wintry on as you, as they did on us."
