BinH (Barbershop in Harmony) We are proud to work with LABBS and Sweet Adelines Region 31 and together we create Barbershop in Harmony (BinH). BinH (Barbershop in Harmony) is a collaboration between the three barbershop organisations in Great Britain, BABS, LABBS and SA R31 to encourage and promote barbershop singing. Currently, BinH hosts the National Mixed Quartet Contest, which cycles between the various organisations' conventions (BABS November, LABBS October, and SA R31 May).
