Vincent is most famous for being one-third of the group "Tony Orlando and Dawn." As an original member to the 1970s group, who later had their own successful television program, she was featured on hit singles like "He Don't Love You (Like I Love You)", "Tie a Yellow Ribbon Round the Ole Oak Tree" and "Mornin' Beautiful".
In 1977, Vincent-Wilson was offered a chance to replace original Supremes member, Mary Wilson in "The Supremes," with members Scherrie Payne and Susaye Greene. However, it was determined by Motown that the group should not continue without any original members. Meanwhile, Wilson still sang as a backing vocalist on Payne and Greene's duet album, "Partners," in 1979, which was originally conceived as a Supremes album. A friend of Payne's, Wilson has also provided backing vocals during her solo concerts.
Wilson continues singing to this day, usually with her sister, Pamela Vincent. In 2006, Wilson and her sister Pamela Vincent, provided backing vocals at the twentieth anniversary concert of the Former Ladies of the Supremes. In January 2007, both Wilson and Vincent provided backing vocals for Payne at a concert in Los Angeles, California. In April 2007, Joyce stepped in as a last-minute replacement for Freddi Poole, who was unable to join her group the Former Ladies of the Supremes, on a tour of Japan. In June 2008, Joyce stepped in to replace Lynda Lawrence on a tour of England. In September 2009, Joyce replaced Freddie Poole as a member of the Former Ladies of the Supremes, which is now billed as Scherrie Payne and Lynda Laurence. Joyce and her sister Pam also perform with the "Inspirational Voices of Free" choir. Joyce and Pam are also members of the group "Tour de 4Force." This 5-piece group includes both Joyce and Pam, and also Jim Gilstrap, Theresa Davis and former Supreme Scherrie Payne.
