The Marvelettes

The Marvelettes was an American girl group that achieved popularity in the early- to mid-1960s. They consisted of schoolmates Gladys Horton, Katherine Anderson, Georgeanna Tillman, Juanita Cowart, and Georgia Dobbins, who was replaced by Wanda Young prior to the group signing their first deal. They were the first major successful act of Motown Records after the Miracles and its first significantly successful girl group after the release of the 1961 number-one single, "Please Mr. Postman", one of the first number-one singles recorded by an all-female vocal group and the first by a Motown recording act.
Founded in 1960 while the group's founding members performed together at their glee club at Inkster High School in Inkster, Michigan, they signed to Motown's Tamla label in 1961. Some of the group's early hits were written by band members and some of Motown's rising singer-songwriters such as Smokey Robinson and Marvin Gaye, who played drums on a majority of their early recordings. Despite their early successes, the group was eclipsed in popularity by groups like The Supremes, with whom they shared an intense rivalry.
