My grandfather turned 70 this past week. Punto Cuban is a Cuban freestyle song from the country-side. The singers go to a party (usually, but not always a birthday or marriage) and sing a long rhyming song about the person of honor. It's amazing to hear them come up with this stuff on the fly.
Extra thanks to Dan, my brother, for filming this while I was taking photos of the event.
The quality is good, but not perfect. It's too bad my dad's video camera didn't work, but others captured it with video cameras too.
