I Will Always Love You (The Bodyguard)

Dolly Parton wrote I Will Always Love You in 1973 as a farewell to Porter Wagoner, her television partner of seven years, whose show she was leaving; she recorded it the following year, took it to number one on the American country chart, and did so again in 1982. Whitney Houston's version, made for Mick Jackson's film The Bodyguard in 1992 and opening with an unaccompanied verse, spent fourteen weeks at number one and became one of the best-selling singles ever released. Parton has said the same song paid her twice, nineteen years apart.
