Cheers was a long-running American sitcom set in a Boston bar, and Kelly was a recurring character connected to Woody Boyd. The Kelly song grew out of that world, becoming a small but memorable musical moment for fans who followed the show's later seasons. As Cheers clips circulated online, short audio moments like this one were lifted for soundboards and fan edits, where they worked as instant shorthand for the show. It remains in use because the tune is recognisable, cheerful, and tied to a comedy many viewers still revisit.
