"The Gateway Singers also included Barbara Dane. They were associated with the Communist Party in the USA, according to Lou Gottlieb's daughter.
Almost every folksinger in the forties, fifties and early sixties were somehow associated with the CPUSA either as members or someone who knew members. That's why folk music was reviled by McCarthy and the HUAC. Some were barely tolerant and didn't become virulent anti until later.
Art, thank you for the nice comments about me. I really enjoy your recordings and contribution to folk music.
