Legendary music composer Nadeem Saifi (of Nadeem-Shravan fame) is making a comeback to Bollywood with upcoming film Ishq Forever and fans of the composer will be delighted to know that the first song of the film was unveiled yesterday. The song, which is titled Bilkul Socha Na, features newcomer Krishna Chaturvedi and Ruhi Singh as they romance each other in South Africa. Though the song video looks heavenly, it seems that shooting the song was quite a Herculean task for the film team.Producer Shabeer Boxwala revealed, “In one of the scenes of the song, the lead pair is seen going into a lake and at the time, as we were shooting during winter, the lake was freezing cold. However, Krishna and Ruhi put up a brave front and entered the lake to give the shot, though it was extremely cold. It was not an easy task at all as the two actors also had to give the right expressions despite the chilly weather and the cold water.”
