I thought Stevie Nicks was downright.....
....attractive and that deep voice was very, well.....sexy.
Patti Smith was about the homeliest women ever. Hanging out with Robert Mapplethorpe didn't help her attractiveness.
Dolly Parton early on before she started wearing 10 tons of makeup. And being such a live wire didn't hurt.
Toni Tennille could give you some pangs.
Sheena Easton was quite a looker with the right hair/makeup.
Bonnie Raitt - looking good
Grace Slick wasn't the BEST looking but enough to give a young boy dreams.
Mary Hopkin, Crystal Gayle, Brenda Lee, Pat Benatar, Petula Clark.
OK, Patti Boyd Harrison Clapton didn't sing, but was she hot or what?
Not my speed but Tina Turner stayed hot the older she got.
Janis Joplin. Well, sorry Janis, your voice and soul were your best attributes. And besides, you barely made it into the 70's
I never thought Joni Mitchell to be 'attractive', but she did have the exotic, brooding look, which I understand is how she really is.
Barbra Streisand doesn't do much for me but she had kind of a 'come back' period when she was in great shape and I think she did a spread in 'Playboy'.
Honorable mention - Carly Simon
