[4] They sang backing on the hits "Ain't No Mountain High Enough" for Diana Ross and "Still Water (Love)" for the Four Tops.

In 1970, Motown producer Norman Whitfield – partly as a response to criticism from Temptations fans that he was using the group as his personal plaything – put together Joe Harris, Billie Calvin, and Brenda Evans to create his own recording act, The Undisputed Truth.

[5] The group's music and unusual costuming (large Afros and white makeup) typified the then-popular trend of "psychedelic soul", which Whitfield had inaugurated.

A number of their singles became minor hits, and many of them were also songs for Whitfield's main act, the Temptations, among them 1971's "You Make Your Own Heaven and Hell Right Here on Earth" and "Papa Was a Rollin' Stone".

Melvin Stewart and Lloyd Williams replaced Calvin Stevenson and Tyrone Barkley for the group's last album.

Former member Billie Calvin later wrote songs for Whitfield's other group, Rose Royce, including the hit single "Wishing on a Star".

Members Billie Calvin and Vee McDonald also made separate solo recordings for the same label, and all three feature on the Tribute to Norman Whitfield album, a Motorcity compilation CD released in September 1996.

[10] McDonald recorded a song entitled "You're My Loveline" (co-written by former Motown lyricists Janie Bradford and Marilyn McLeod), which was released in the UK.
