In her book "Dreamgirl", Mary writes about going to Chicago with James Jamerson, Joe Hunter, Hank Cosby and the Andantes for session work. She's mentions working with Jerry Butler on "A Teenie Weenie Bit Of Your Love' (aka "Just A Little Bit") and John Lee Hooker on "Boom Boom". The problem with the last one is that there are no backup singers. Is this the song she was thinking of ??
