Barcelona was written by Freddie Mercury and Mike Moran and recorded as a duet with Spanish soprano Montserrat Caballé, whom Mercury greatly admired. First released in 1987, the song blended rock and opera in a style that became closely linked to the city itself. After Mercury's death in 1991, it was reissued in 1992 and used as the anthem for the Barcelona Olympic Games, reaching a new global audience. Its revival kept it associated with celebration, pride and large sporting ceremonies online.
