The song is based upon a direct vocal sample from American dance producer Matthew Dear's 1999 track, "Hands Up for Detroit." Le Grand explained to 1Mix Radio
why he borrowed that particular vocal, and why he loves Detroit as a city. He said: "It was a reference to the days of Detroit Techno, the producers and the sound that came out at that time were a big influence to me and it's great to hear that sound coming out again lately. I never knew the track would be so big. I think you always know when you've got a hit of sorts on your hands just from playing it out in clubs, and the reactions of people around you. But I never expected in my wildest dreams that the track would go to the number 1 spot in so many charts around the world. That was a very big point in my career for one, but one that I think I've now built on from."
