It was darn nigh impossible for women in rock in the '70s.
There wasn't a mold if you were a woman and you were in the entertainment in the '70s. You were probably a disco diva or a folk singer, or simply ornamental. Radio would play only one woman per hour.
We want to live at any price; so we cannot burden ourselves with feelings which, though they might be ornamental enough in peace-time, would be out of place here.
