"JCB" (or "JCB Song") is a song by English folk music duo Nizlopi, written by members Luke Concannon and John Parker. Concannon wrote the lyric at his parents' house, drawing inspiration from his father, Kieron Concannon, and later composed the song with Parker. The theme of the song's lyric stems from a moment in Concannon's childhood when his father picked him up from school in a JCB digger (or backhoe loader) and his reflections on how his peers bullied him for having dyslexia. The song tells the story of a similar boy who is fascinated with both his father and the vehicle on which they ride. He imagines his father as a hero, comparing him to several famous figures such as Bruce Lee and B. A. Baracus, and pretends to torment bullying on the playground as a "Tyrannosaurus rex". Nizlopi recorded the song at FDM Records' studio and included it on their debut album, "Half These Songs Are About You", released in 2004.
