The 1974 song "Lady Marmalade" was written by Bob Crewe and Kenny Nolan, originally for Nolan's disco group. The song is famous for the repeated refrain of "Voulez-vous coucher avec moi?" in French as part of the chorus, a sexually suggestive line that translates into English as: "Do you want to sleep with me?".

The song truly became a popular hit when it was recorded by the American funk rock group Labelle and held the No. 1 spot on the "Billboard" Hot 100 chart for one week, and also topped the Canadian RPM national singles chart. In 2021, the Library of Congress selected Labelle's version for preservation in the National Recording Registry for being "culturally, historically, or artistically significant".

The song has had many cover versions over the years. In 1998, girl group All Saints released a cover of the song that peaked at No. 1 on the UK Singles Chart. The 2001 version by singers Christina Aguilera, Mýa, Pink and rapper Lil' Kim, recorded for the movie "Moulin Rouge!" soundtrack. It was also a No. 1 hit on the "Billboard" Hot 100 for five weeks, and also a No. 1 hit in the UK. "Lady Marmalade" was the ninth song to reach No. 1 by two different musical acts in America.

Additionally, this song with the popular lyric "Hey sista, go sista, soul sista, flow sista" as recorded by the girl group Labelle was seen as prominent/conspicuous. The song’s inspiration was from Crewe’s observations of New Orleans, Louisiana; thus, he decided to write about a prostitute.
