Until today, I labored under the impression that Don Cornelius was involved in the successful early '70s group, The Cornelius Brothers and Sister Rose.
I don't believe so, but Cornelius did have a hand in other musical acts, at least during Soul Train's early years. He and record promoter and songwriter Dick Griffey launched Soul Train Records around 1973, but Cornelius his interests in the company back to Griffey a couple of years later. One of those was Shalamar, which two of its prominent members (Jody Watley and Jeffrey Daniel) were originally Soul Train dancers.
