Marianne's 60's work was definitely folky in her early days and fits well within this page. Like Francoise Hardy, the chanteuse, crossing between folk and pop. As tears go by, come and stay with me, this little bird, her version of yesterday.. are very 60's folk in style, even with the orchestration. Her original voice had a wonderful refined quality. Sadly, it is proof that what you do to your body can decimate the whole timbre of the voice.
Still, she went on to adapt to the loss of her original voice, and used it as best she could, with fans largely accepting the hit and miss, husky cracked delivery, plus recordings, bringing cult status. She left her mark in the UK. and will always appear on 60's golden oldie radio shows with her couple of period classics.
