This is the third single by Scottish DJ, singer, songwriter and producer Calvin Harris, from his third studio album. He recorded two versions; the original radio edit features American R&B Artist Ne-Yo and was premiered on Kiss 100 on March 2, 2012. A club remix, titled "Let's Go (Calvin Harris Remix)" was premiered on Pete Tong's BBC Radio 1 show on the same night.
The song was used in the UK to soundtrack a footballer-starring Pepsi Max advertising campaign featuring Lionel Messi, Didier Drogba, Fernando Torres, Frank Lampard, Sergio Agüero and Jack Wilshere.
Originally a chart-topper for Steve Lawrence in 1962 chart-topper, "Go Away Little Girl," became the first song of the rock era to be taken to #1 by two different artists when Donny Osmond's cover version also reached the summit in 1971.
