Super Scot Evelyn Glennie is one of the world's most brilliant percussionists. She has also been profoundly deaf since childhood.
But don't dare mention her deafness, especially if Evelyn's ultra-protective husband, Greg Malcangi, is around.
For that's one subject Evelyn now treats as strictly taboo.
Evelyn Glennie's talents are without question, her stage shows electrifying and the range of 700 instruments she plays awesome.
She has made a fortune, not because she's deaf, but because she's a musical genius.
Yet I was only minutes inside the door of Evelyn's large, mock-Tudor home in a quiet Cambridgeshire village, when husband Greg told me sternly - without introducing himself - that Evelyn "will not be answering questions about her deafness."

Minutes later, I was greeted by Evelyn herself, a waif-like Size 8 in black satin trousers.
In a room filled with more exotic musical instruments than furniture, Evelyn admits: "I'm not domesticated at all.
"We don't have a lot of furniture, because I don't buy just for the sake of it. Where some women buy clothes and make-up, I'd rather buy instruments. It's an addiction."
