You misunderstand, there is no need to mix up the Black and Tan, the ingredients are blended before bottling/canning.
As far as black and white being another name for a chocolate milkshake, read the previously posted URL. I speak from experience with a year of after school soda jerking at a real soda fountain almost 60 years ago in Philadelphia.
