I'm not a big fan of Marianne F, but watched this out of curiosity.
My impression is that she had a very pretty face which opened doors for her, and had a lot of luck in meeting famous musicians along the way, who made things happen for her. Her voice wasn't great, it was more a case of having the right face, in the right place and time.
I'm not sure that the same sort of career would be possible for a young pretty woman starting out in the music industry today - it's all so very different and there isn't so much money to be made from selling records (now CDs) as so many people stream free music online. Did anyone else watch this, and if so, do you have similar thoughts?
