The Undisputed Truth was originally a trio, put together by fragments left from a couple of Motown groups. Joe Harris came from The Preps and had been involved with the Ohio Players in the 60's. Billie Rae Calvin and Brenda Joyce had a past history in The Delicates and as backup singers for Diana Ross, Four Tops and Edwin Starr. The year was 1970 and the man behind this project was famous Motown producer Norman Whitfield.

Undisputed Truth has always been regarded as some sort of forever-and-ever warm up band, and not as a real group.
