"Lady Marmalade" is a song written by Bob Crewe and Kenny Nolan that is famous for the French refrain of "Voulez-vous coucher avec moi, ce soir?", which is a sexual proposition that translates into English as: "Do you want to sleep with me, tonight?" 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.
