Viva Las Vegas is the title song from the 1964 musical film of the same name, performed by Elvis Presley as racing driver Lucky Jackson. Written by Doc Pomus and Mort Shuman, it became one of Presley's most recognisable hits and a lasting anthem for the city itself. Online, the bright chorus is reused in short videos, edits and memes to signal luck, wealth, nightlife and a Vegas-style entrance, keeping a 1960s film song familiar to audiences who may never have seen the original movie.
