Los Blue Caps – a rock band from Paraguay. Several world-popular genres of music, such as rock are fairly new in the Paraguayan music scene. This is because of the fierce dictatorship enforced by former President Alfredo Stroessner during his mandate from 1954 to 1989, in which he banned all forms of liberal expressions. Despite that, a few rock groups were formed in the 1970s such as The Aftermad’s and The Blue Caps.
Here is their song Hoy Salgo Contigo , with the charming original music video from the 70´s

That was very cute. It actually made me think of the American group, The Monkees. They did that kind of silly, fun video styling.
