Cheers ran on American television from 1982 to 1993, and its opening theme, Where Everybody Knows Your Name, became closely tied to the Boston bar at the centre of the show. Written for the series and performed over its opening credits, the song outlived the sitcom through reruns, singalongs and nostalgic references. Online, the short theme is now used as shorthand for familiarity and community, instantly signalling a place where regulars gather, even in videos that have nothing to do with the original show.
