Whilst Eliza And The Bear perform Light It Up, a couple of guys dance their socks off in this uplifting promo from Francis Wallis. They're the cleaners - one office, one waste disposal – who show us just how much fun can be had, once the coast is clear...

FRANCIS WALLIS:

"I wanted to create a running unsung heroes of the night theme to the video. There’s something about seeing people who love jobs that most would hate to the core that I felt could be as strangely uplifting as the track itself is."
