Has nothing to do with Julie Andrews, she pronounced it correctly -- for the United States usage.
It is indeed "
Ti" here in the US of A, "
Si" in most EU countries, just another one of those language difference things.
Why that is, I do not know.
While you are
ageing gracefully using the Queen's English, we here in the States are
aging gratefully, and we do appreciate the
humourous nature of such slight differences in language, as John has pointed out rather
humorously recently.
But what I want to know is, "What colour is
Si anyway?"
And, "Isn't
Si the same as
Haitch when in the key of Do?"
