I want to know the answer to the following question:
What racial group was primarily involved in babershop a cappella in its earliest days?
All the background I'm provided with is that "In 1938, the first formal men's barbershop organization was formed, known as the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America (S.P.E.B.S.Q.S.A), and in 2004 rebranded itself and officially changed its public name to the Barbershop Harmony Society (BHS).". Is that enough to answer the question?
Answer: no
