The Undisputed Truth

The Undisputed Truth is an American R&B and psychedelic soul group, founded by producer Norman Whitfield. The original members were Joe Harris, Billie Calvin, and Brenda Evans. In 1973, Billie Calvin and Brenda Evans left the group and were replaced by Virginia McDonald ("Vee"), Tyrone Barkley ("Lil Ty"), Tyrone Douglas ("Big Ty"), and Calvin "Doc" Stephenson. The group followed Norman Whitfield to Whitfield Records in 1975 after leaving Motown. Yvonne Stevens (aka Taka Boom) joined the group when Virginia McDonald and Tyrone Douglas left. During the late '70s, the line-up often included musicians from Whitfield's other group, Rose Royce. The last album of the group featured Joe Harris, Marcy Thomas, Melvin Stewart, and Lloyd Williams.
