Have you seen the movie 'The Motorcycle Diaries' ? If you've ever wondered who Che Guevara was then I'd recommend it. It shows Che and friend Ernesto on a journey through South America during 1951-2. My favourite part of the film is when they at a party where the song 'Chipi Chipi' is being performed. It's one of those songs that has got lodged in my head, forcing me to seek it out and purchase a copy of the soundtrack. Here is the clip from the film itself.
I also found this wonderful version by a band called Los Gofiones who seem quite unique.
