LaBelle Biography (Wikipedia)
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 Philadelphia/Trenton areas, the Ordettes and the Del-Capris, forming as a new version of the former group, 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 and reformed 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-rock costumes, the group found success with the proto-disco smash "Lady Marmalade" in 1974, leading to their parent 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 on the cover of Rolling Stones Magazine
