Mumbai in late May 2011. The first stage of shooting was completed in early July 2011. Filming resumed at the end of the month, and continued until mid-August 2011. Initially, the London scenes were to be shot in September after the release of Mausam (2011), another film starring Kapoor. However, the release date was postponed one week to 16 September, causing the pre-release promotions to conflict with the existing shooting schedule. Chopra was scheduled to film Barfi! (2012) in July, but director Anurag Basu agreed to move filming to September so that Kohli could film with both Chopra and Kapoor in July. The London portion, where Kapoor and Chopra portray two college students, was filmed at the University of Nottingham's Jubilee Campus and the Stratford-upon-Avon. Filming ended in January 2012 with a four-day long song shoot in Aurangabad, Maharashtra. Soundtrack The film's soundtrack was composed by Sajid–Wajid, with lyrics written by Prasoon Joshi. The album consists of five original songs and two remixes. The vocals were performed by Wajid, Rahat Fateh Ali Khan, Mika Singh, Shreya Ghoshal, Sonu Nigam, Sunidhi Chauhan and Shaan. It was released on 6 June 2012 by T-Series. The soundtrack received positive reviews from critics. Noting it as a "a very good success, especially so since it has melody at its base", Joginder Tuteja of Bollywood Hungama gave the album a rating of 4 out of 5, writing, "Sajid-Wajid and Prasoon Joshi can be rest assured that their music would reach out to the masses in a big way and find very good appreciation." Hindustan Times gave it a rating of 3.5 out of 5, praising its "youthful fervour" and adding that "the album manages to capture the essence of three different periods on which the film is premised." The Times of India gave it 3 out of 5, also commenting on its fresh and youthful feel, and calling it "another hit album" despite the fact that "it falls short in some songs". Koimoi gave the "good album" 3 out of 5 and wrote, "as a package it has enough ingredients in it that would ensure that the songs do catch your attention when they are played on screen." BBC identified the album as "A crowd pleaser featuring the cream of the industry's playback singers." Release Several stills from the films were released to the media before the trailer, which was posted online on 5 April
