In 1969 they recorded and released their debut full-length, Philosophy of the World on Third World Records. They were joined by their sister Rachel Wiggin on bass for the song, "That Little Sports Car." It defied the expectations of their parents, who said "imagine the girls to be inevitably bound for stardom", and they disappeared without a trace.
In 1975, the sisters again entered the studio although the death of their father/manager, Austin Wiggin, resulted in their not being published for years as well as the group's dissolution. Years after their break-up their debut was rediscovered and championed as an example of art brut/outsider music.
