Happy to accept a disqualification (either on the grounds of not quite being rock, or not quite being 70’s – though she was signed to a label in '79), but I have to put in a mention for Laura Branigan… on whom i had a crush just from her album photo and voice.
I didn’t realise until i checked her bio just now that she had died in 2004. Sad.
I have to say, you’ve not changed my mind, but you’ve made a very strong argument here. Kate has a whole Emma Samms/Counselor Troi’s love child thing going on that hots me up pretty good.
