The Cantina Band music comes from Star Wars: A New Hope (1977), where it plays in the Mos Eisley cantina as the band Figrin D'an and the Modal Nodes performs for its alien patrons. Composed by John Williams in a lively jazz style, the tune became one of the film's most recognisable cues. Online, creators reuse it to signal a strange bar, a gathering of odd characters or a sudden change of scene, keeping the original scene's playful, out-of-this-world atmosphere alive in short edits.
