I was, for a while, a member of the Mainliners chorus in Bryn Mawr, PA
It was a rewarding and enriching experience. The demanding schedule of rehearsals for competitions was the only reason I stopped going to meetings. I would advise anyone who enjoys singing and would like to improve his vocal skills to join a chapter and stand on the risers with as fine a crowd as I have ever known. (I still have a few of the arrangements including what they call Barbershop Polecat Songs, which are the numbers that all the choruses sing about the same.)
