I only barely know of her. Not much. I grew up with a couple of sisters who were heavily into fashions, like most young girls are. When Dame Lesley Lawson DBE dies, there will be a humongous hullabaloo about it. Her working name was Twiggy.
If you were around then at all, and aware of the British Style & Music Invasion at all, you would have heard of Twiggy.
Oh yes, she's famous because she had a small part in Blues Brothers.
