It's ok, in its place, but it flatly AIN'T folk! It has its own 'tradition', but not folk tradition. You can't jam everything under one roof.

Barbershop, like Bluegrass, seems to assume almost everything can be adapted to their style... "Sweet Adeline" is fine, but this morning I heard a very Barbershop version of "Time Has Made a Change in Me"...the tune was sorta recognizable, but the harmonies altered things a lot!...and the 'feel' of the song was sacrificed for sound and rhythm.
