The death of Montserrat Caballé has led us to remember his great interpretations. One of the best known by the profane and remembered public is the one she made with Freddie Mercury "Barcelona" because for a few moments the opera singer was approaching pop music. The singer had been commissioned to create a hymn for the opening of the Olympic Games in Barcelona to be held in 1992. This happened in 1988 and Caballé contacted Fredy Mercury to propose to work together. The song was composed by Mercury and he is the main singer and she is the support voice in operatic tone.
The theme was presented in Barcelona at the ceremony of delivery of the Olympic flag that came from Korea. The singer played it at the Olympic Games in Barcelona but without Mercury who had died a year earlier.
