Jackie (Sigmund Esco Jackson, born May 4, 1951)
He wanted to be a baseball player but quickly took to his role as co–lead singer of both the Jackson 5 and the Jacksons. Jackie produced two solo albums, 16 years apart (1973's Jackie Jackson and 1989's Be the One). His current project is launching new stars through his label, Jesco Records. One longtime hopeful? His son, rapper Siggy, a.k.a. Dealz.
