The song comes from The Lord of the Rings film trilogy, where hobbits Merry and Pippin perform it at the Green Dragon inn in the Shire. Known as the Green Dragon song, it celebrates good ale and good company, echoing the drinking songs Tolkien wrote into Middle-earth culture. Clips of the performance circulate on soundboards and in edits because the chorus is short, recognisable to fans, and instantly sets a medieval tavern mood without needing any explanation or setup from the scene around it.
