Task: Question Generation
Input (English): Passage: "Shine" was written by Pharrell Williams and Gwen Stefani, and produced by Williams. In November 2014, the pair announced that they were collaborating on a recording for the animated film Paddington. They had previously worked together on four singles: "Hella Good" (2002), "Can I Have It Like That" (2005), "Hollaback Girl" (2005), and "Spark the Fire" (2014).Williams initially pitched "Shine" as a song for No Doubt, of which Stefani was lead vocalist. She immediately noticed similarities between the demo and her music with No Doubt and played it for the rest of the band to get their reaction. No Doubt recorded their version in late 2014. According to Rolling Stone, Stefani was collaborating with the band for a song for the Paddington soundtrack. Despite this announcement, Rolling Stone's Patrick Doyle suggested that it would be recorded by Williams and Stefani instead.In an official statement, film executive Bob Weinstein called Stefani and Williams "the perfect artistic duo", saying their work "brought to life the charm that Paddington represents". Stefani said her involvement was motivated by her personal connection to the film's setting through her marriage to English musician Gavin Rossdale. She added that the film and the track allowed her children to recognise their origins. Williams considered the song to be "a wonderful opportunity, as a parent, to contribute to something as classic, authentic and generational to all of our lives, as Paddington Bear"; Stefani said that she was "honored to join forces with Pharrell and be part of bringing this beloved classic to life for Paddington's next big adventure". Williams called the song "a trailer into a wonderful family experience" and developed its concept from his children's interest in Paddington Bear.
