It was produced and written by Labrinth and Da Digglar, and was released on 27 September 2010 on Simco Ltd and Sony Records.

In a special Live Lounge, Leona Lewis performed an acoustic cover of the song at the Hackney Empire.

Robert Copsey of Digital Spy gave the song a positive review: ...for starters Labbers has something no amount of studio trickery can create: soul.

While the track's beat is reminiscent of many a Taio/Derülo/Ne-Yo number, his passionate performance and heartfelt lyrics about letting go of negativity set him strides apart from the current crop of robopop vocalists - and with a chorus that fuses gospel, funk and R&B, it certainly feels worthy of a eureka moment.

As of March 2012, "Let the Sun Shine" has sold 311,529 copies in the United Kingdom.
