This features the vocals of Glee star Alex Newell (he plays transgender student Unique Adams) and Sean Bass, whose sister Sharna Bass guested on Clean Bandit's hit single "Extraordinary" when she was 16.
Olly Alexander from Years & Years co-wrote the song. The synth-pop trio Years & Years supported Clean Bandit on their 2014 UK tour.
The song's music video was directed by Wlodek Markowicz and Karol Paciorek, a Polish duo whose entertainment show Lekko Stroniczy has found success on YouTube. The clip finds an ordinary-looking London bus driver performing the track during his day at work.
Fifty Microsoft Lumia smartphones were used for a bullet-time sequence as part of Clean Bandit's sponsorship deal with the company, which sees the band star in TV ads for the phone.
The Prince-penned "Manic Monday" was the first song The Bangles heard coming from a car radio, but "Eternal Flame" is closest to Susanna's heart, perhaps because she sang it in "various states of undress."
