The song, "I Will Always Love You" was written and originally recorded in 1973 by American singer and songwriter Dolly Parton. Her country version of the track was released as a single in 1974 and was written as a farewell to her one-time partner and mentor Porter Wagoner upon Parton's decision to pursue a solo career.

Parton's version of "I Will Always Love You" attained commercial success, twice reaching number one on the Billboard Hot Country Songs chart—first in June 1974, and again in October 1982, with her re-recording. With this achievement, Parton became the first artist ever to earn a number one record twice with the same song.

Whitney Houston recorded a cover version of the song for the 1992 film The Bodyguard. Her single spent 14 weeks at number one on the Billboard Hot 100 chart. It has since become one of the best-selling singles of all time and it remains the best-selling single by a woman in music history. Houston's version of "I Will Always Love You" re-entered the charts in 2012 after her death, making it only the second single ever to reach the top three on the Billboard Hot 100 in separate chart runs. The song has also been covered by many other significant artists including Linda Ronstadt and John Doe.

Country music singer and songwriter Dolly Parton wrote the song in 1973 for her one-time partner and mentor Porter Wagoner, from whom she was separating professionally. She recorded it in RCA's Studio B in Nashville on June 13, 1973. "I Will Always Love You" was issued on June 6, 1974 as the second single from Parton's thirteenth solo studio album, Jolene (1974). Parton later re-recorded the song in 1982, when it was included on the soundtrack to the film The Best Little Whorehouse in Texas. In addition to the 1982 re-recording for The Best Little Whorehouse in Texas's soundtrack, Parton's original 1974 recording of the song also appeared in Martin Scorsese's film Alice Doesn't Live Here Anymore, and the 1996 film It's My Party. The song also won Parton Female Vocalist of the Year at the CMA Awards, in 1975.
