From the wiki: “‘Lady Marmalade’ is a song written by Bob Crewe (‘Silhouettes‘, ‘Silence is Golden‘, ‘The Sun Ain’t Gonna Shine Anymore‘, ‘Can’t Take My Eyes Off You’) and Kenny Nolan (‘My Eyes Adored You’, ‘I Like Dreamin”), inspired by Crewe’s first-hand observations of New Orleans and made famous for its sexually suggestive chorus of ‘Voulez-vous coucher avec moi (ce soir)?’ (‘Do you want to go to bed with me (tonight)?’).
“After it was first recorded as a demo by The Eleventh Hour, a group made up of studio musicians, fronted by co-writer Nolan on vocals, ‘Lady Marmalade’ was first released in 1974 as a track on the Eleventh Hour’s Greatest Hits LP which did not chart. Meanwhile, co-writer Crewe showed the song to Allen Toussaint in New Orleans; Toussaint then decided to record the song with Labelle, whose label (Epic Records) had hired him to produce their label debut, Nightbirds.
