"Lady Marmalade" is a song written by Bob Crewe and Kenny Nolan, originally for Nolan's disco group the Eleventh Hour. 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: "Will you sleep with me?" The song first became a popular hit when it was recorded in 1974 by the American funk rock group Labelle and held the number-one 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".

Labelle was an American funk rock band that originated out of the Blue Belles, a girl group who were a popular vocal group of the 1960s and 1970s. The original group was formed after the disbanding of two rival girl groups in the area around Philadelphia, in Pennsylvania, and Trenton, in New Jersey: the Ordettes and the Del-Capris, forming as a new version of the former group, then later changing their name to the Blue Belles. The founding members were Patti LaBelle, Cindy Birdsong, Nona Hendryx, and Sarah Dash.
