I Will Always Love You is a song by American singer-songwriter Dolly Parton that appeared in the episode Mayored to the Mob. The country track was released on June 6, 1974 as the second single from Parton's thirteenth solo studio album, Jolene (1974). Recorded on June 13, 1973, the singer wrote the song for her one-time partner and mentor Porter Wagoner, from whom she was professionally splitting at the time. I Will Always Love You received positive comments from critics and attained commercial success, reaching number one on the Billboard Hot Country Songs chart two times. With the accomplishment, Parton became the first artist ever to earn a number one record twice with the same song as a singer, and three times as a writer. "I Will Always Love You" is the second song ever to reach the top three on the Billboard Hot 100 in separate chart runs.

Whitney Houston recorded a version of the song for the 1992 film The Bodyguard which is one of the best selling singles of all time. Leavelle, Homer's professional bodyguard trainer, sings this song in "Mayored to the Mob" as a reward for the entire graduating class, but he sang it so badly that the students left, interpreting the song as a sign that it's time for them to leave.
