 The Supremes had released their 29th and last studio album, "Mary, Scherrie & Susaye", in October 1976, just nine months before they officially disbanded as a group.During June 1977, Wilson decided to leave the Supremes (who were managed by her then-husband Pedro Ferrer at the time).Prior to her husband becoming the manager of the group, Wilson and Berry Gordy had an argument backstage at the Frontier Hotel in Las Vegas in 1970 (the same night Diana Ross made her farewell performance with the group to start a solo career).
