In the last Filichia column at Kritzerland, he discusses the Goodspeed Opera House's production of "Hello, Dolly!" with Klea Blackhurst and writes:
Even when she joins the chorus in “Put on Your Sunday Clothes,” her voice stands out – not in that obnoxious way that Julie Andrews sounds when she’s showing off at the end of “Edelweiss.” Blackhurst is simply being a good team player who’s doing her job in singing; can she help it if her voice just happens to be heard among the rest?
For the record, and of course it's only my opinion, Julie Andres was never, in any way, obnoxious in her vocals for "The Sound of Music"...and I have always adored that she went up an octave on those final notes of "Edelweiss" at the folk festival. In fact, since the entire audience was singing, too, it reminded you that the Von Trapp family was on the stage singing.
There, I've said it and feel much better.
