Labelle was an American all-female singing group who were a popular vocal group of the 1960s and 1970s. The group was formed after the disbanding of two rival girl groups in the area around Philadelphia and Trenton, the Ordettes and the Del-Capris, forming as a new version of the former group, then later changing their name to the Blue Belles (later Bluebelles). The founding members were Patti LaBelle (formerly Patricia Holt), Cindy Birdsong, Nona Hendryx, and Sarah Dash.

As the Bluebelles, and later Patti LaBelle and the Bluebelles, the group found success with ballads in the doo-wop genre, most notably “Down the Aisle (The Wedding Song)”, “You’ll Never Walk Alone”, and “Over the Rainbow”. After Birdsong departed to join the
Supremes in 1967, the group, following the advice of Vicki Wickham, changed its look, musical direction, and style to re-form as Labelle in 1971. Their funk rock recordings of that period became cult favorites for their brash interpretation of rock and roll and for dealing with subject matter that was not typically touched by female black groups. Finally – after adapting glam rock and wearing outlandish space-age and glam costumes – the group found success with the proto-disco smash “Lady Marmalade” in 1974, leading to their album Nightbirds, which achieved gold success. They are notable for being the first contemporary pop group and first black pop group to perform at the Metropolitan Opera House. They were also the first black vocal group to appear on the cover of Rolling Stone.
