Do you have a good source for that?

Most biographies have Jørn Utzon declining invitations to attend the opening and to later design the interiors in Australia (he did so remotely) after some major fallings out over cost with a new government after those that intially commissioned the work left.

Who hasn't been tripped up by an ex partner with an interest in the occult?

Well, Bill Bryson wrote about it in his book down under. Also, when I was in Sydney last September, I asked the tour guide about it, and she confirmed that it was true. He never got to see his creation because he was turned away at the border.

Who was turned away at the border though?

The architect and designer Jørn Utzon apparently never attempted to return after a falling out over funding and refused two invitations (to the opening and to return and design interiors ).
