Dunno, but there was, and possibly still is a female barbershop group called 'The Sweet Adelines'. I remember seeing them around 30 years ago when a U.S. barbershop contest was televised. I think they were a Barbershop 'choir', but memory could well be at fault. The best male barbershop quartet I ever heard was in the same competition. They were called 'The Pacific Airs'.
