Cuba's music is at the core of its national identity and for the past seven years, it has also been at the heart of an international legal battle When Buena Vista Social Club became a huge global hit, Cubans thought they could cash in and make money from their old music. But as soon as their re-releases hit the shops Peer music - the largest privately owned American music publishing company - took the Cubans to court. They claimed that their founder Ralph Peer had bought the rights to the very same songs way before the Cuban revolution back in the 1930s. This is the story of the fight for Cuban music between the Cuban state music company and America's Peer Music.
