Barcelona (Freddie Mercury and Montserrat Caballé song) sessions. The song was co-written by Mercury with Mike Moran, who also appeared in its video and played piano and all keyboards for the studio recording. The song starts with an orchestral introduction, which fades and is followed by Mercury and Caballé singing alternately their solo lines, sometimes merging into a duet. When singing the chorus "Barcelona" and a few other parts for the studio version, Mercury dubs over his voice in his usual multi-tracking style. Mercury leads the song whereas Caballé provides a powerful "background" soprano. Since Caballé covers the soprano part, Mercury sings in his natural baritone voice
Montserrat and an ex-situ captive breeding population has been set up in partnership with Durrell Wildlife Conservation Trust, Zoological Society of London, North of England Zoological Society, Parken Zoo and the Governments of Montserrat and Dominica. Releases from this programme have already taken place in a hope to increase the numbers of the frog and reduce extinction risk from Chytridiomycosis. The national bird is the endemic Montserrat oriole ("Icterus oberi"). The IUCN Red List classifies it as Vulnerable, having previously listed it as Critically Endangered. Captive populations are held in several zoos in the UK including: Chester Zoo, London Zoo, Jersey
