You're thinking Karla Devito (no relation to Danny), and yes she did marry Robbie Benson. She was so hot in that video.
Thanks for the correction. I have heard of Karla Bonoff. Probably when I was more aware of the fast-paced, live-on-the-razor's edge, laugh in the face of death world of garage band rock and roll. About the only new stuff in the past 10 years is Sarah McLachlan.
