Publio Delgado, a Spanish musician, wrote "Dou hua," a guitar and percussion piece, in 2012.
Or that's what he thought. Video footage of him singing in the bathtub when he was 1 year old reveals that he's had the melody rolling around in his head for a long time.
In this invigorating music video, Delgado harmonizes with himself, adding an instrumental backdrop to the vocals from his much younger self.
