The Supremes performing on "The Ed Sullivan Show" on December 21, 1969. The Supremes without Ross made their final appearance altogether on "Ed Sullivan" on February 15, 1970. Diana Ross & the Supremes gave their final performance on January 14, 1970 at the Frontier Hotel in Las Vegas. At the final performance, the replacement for Diana Ross, Jean Terrell, was introduced. According to Mary Wilson, after this performance, Berry Gordy wanted to replace Terrell with Syreeta Wright. Wilson refused, leading to Gordy stating that he was washing his hands of the group thereafter. This claim is also made by Mark Ribowsky. After
Diana Ross weight, and alcoholism, Florence Ballard was fired from the Supremes by Gordy in July 1967, hiring Cindy Birdsong from Patti LaBelle and the Blue-Bells as Ballard's replacement. Gordy renamed the group "Diana Ross & the Supremes", making it easier to charge a larger performance fee for a solo star and a backing group, as it did for other renamed Motown groups. Gordy initially considered Ross leaving the Supremes for a solo career in 1966 but changed his mind because the group's success was still too significant for Ross to pursue solo obligations. Ross remained with the Supremes until early 1970.
