I have just received news of a new song written about the sinking of the ship Ciudad de Barcelona in 1937. I have no detailed information to pass on about the song itself but there is a 20 second sound clip available using this link. https://chuffed.org/project/solidarity-park   The link will take you to a site where it is possible to download the whole song in exchange for a donation towards the establishment of a new memorial devoted to the brigadistas who were drowned when the ship was sunk off the coast of Catalonia while bringing over 300 volunteer fighters to defend the Spanish Republic against fascism in 1937. the site displays photographs of the proposed memorial which is based upon reports of the brigadistas singing The Internationale as the boat sank.
