Cook, do you know Cock Robin? They were an American band that had a few hits in Europe in the mid-80s. The biggest one was "The Promise You Made". The band had a female singer Anna LaCazio, though she had a more supportive role next to the leadsinger, a bit like Signy Toly Anderson had. Their singing brings up vague memories of Jefferson Airplane, just a bit, but the drama and passion is there.
