Vocalist Oma Heard – also known by her married name, Oma Drake – had two short stints at Motown in the 1960s, first as a solo artist and later via the Chisa label as part of the obscure girl group Dorothy, Oma, And Zelpha. She became a background singer in the ’70s, on records from artists like John Lee Hooker and Billy Preston. She is mis-identified as “Oma Page” (another, different Motown singer, wife of Billy Page) on demos cut with Marvin Gaye which were released in the 1990s.
