Barcelona is a collaborative studio album recorded by Freddie Mercury, frontman of popular British rock band Queen, and operatic soprano Montserrat Caballé. It was released in 1988. After Barcelona was selected to host the 1992 Summer Olympics, Mercury was approached to write a song as a theme for the forthcoming games. The idea was to create a duet with Caballé, as she was from the city. He had been a long-standing admirer of her and she in turn grew to respect his talents very highly.
