Beautiful song titled World Inside My Heart by Mohicans. Deep Spirit of Native Americans. Origination: Ailein duinn ("Dark-haired Alan") is a traditional Scottish song for solo female voice, a lament that was written in Gàidhlig for Ailean Moireasdan ("Alan Morrison") by his fiancée, Annag Chaimbeul ("Annie Campbell"). In 1788, Ailean, a sailor, set off with his ship to Scalpay, Harris, where he and Annag would be married. In a tragic twist, the ship sailed into a storm and all on board were lost. Annag was devastated and lost her will to live, dying several months later. Her body was later discovered on the beach, not far from where Ailean's body was found. Before she died, Annag composed this lament for her lost love.
