Un Poco Loco

"Un Poco Loco" is the most purely joyful piece in Coco's score — a son jalisco number built on rapid guitar, vihuela, and the kind of exuberant percussion that seems designed to make it impossible to remain still. Anthony González and Gael García Bernal play off each other with genuine comedic chemistry, Bernal's Héctor using improvised lyrics to needle and redirect while González's Miguel insists on musical integrity amid chaos. The production is authentically Mariachi-adjacent without being pastiche — the musicians clearly understand the tradition they're working in, and the recording captures the ensemble's interaction with a live-performance energy. Lyrically, the song operates through a series of increasingly absurd love comparisons ("you're as crazy as a dancing, furry toad"), with García Bernal's improvisations getting progressively wilder while González struggles to keep the melody intact. The comedy derives from the collision between the song's formal beauty and the chaos introduced into it. Within the film, the song functions as a stage performance but also as the beginning of Miguel and Héctor's unlikely friendship — the moment when competition becomes collaboration. Culturally, it celebrates the son jalisco tradition with genuine love and technical accuracy. Best heard when you need to move — it is physically difficult to listen to this song sitting completely still.
