Personally, I only think of the "Hymn of the 26th of July" as a song of the Cuban Revolution of the 1950's. I don't think that were any references to either socialism or Communism anyway in the song. Other than that, I enjoyed listening to it because it had so much meaning in historical terms. ✊👍
Compañero Robert: En efecto, la Marcha del 26 de Julio no hace referencia alguna al Socialismo, al Comunismo o al Marxismo-Leninismo. Recomiendo escuchar su letra cantada.
