I Will Always Love You was written and first recorded by Dolly Parton in 1974 as a farewell to her mentor Porter Wagoner. Whitney Houston recorded a new version for the 1992 film The Bodyguard, and her powerful ballad arrangement became one of the best selling singles of all time. The final chorus in particular was widely shared in films, talent shows and later online edits. Its mix of love and goodbye keeps it in use for both sincere tributes and ironic dramatic exits.
