It wasn't like Berry Gordy didn't try "to promote white acts to their mixed audiences"- they were doing it from the beginning with
Nick and The Jaguars, Connie Van Dyke, Debbie Dean, Bobby Breen, Tony Martin, Connie Haines, most of the Mel-O-Dy label when
it became Country focused, the Underdogs, The Lewis Sisters, Little Lisa, the Dalton Boys, R. Dean Taylor are just a few. None
of these acts achieved much success. It was later with Chris Clark and especially Rare Earth that Motown saw some chart action with their
white artists.
