John Huston: Pronunciation?

[Jan Ivarsson TransEdit]

I have heard several different pronunciations of the name of film director John Huston. RHUD gives "hyoostn", but Halliwell's Film Dictionary says that his father Walter changed the spelling of his name from Houghston into Huston. Did he also change the pronunciation? One of my (oral) sources, active in fim business, said that he did not - but how reliable he was I do not know.  (My [British English] pronouncing dictionary, Jones-Gimson, only has Houghton, with the first vowel pronounced either as in "born" or in "now" when used as a surname.)
How do members of the family pronounce their name? I suppose that some member of the ADS knows, as usual.
