I'm sure the polka-dot "dress" (I'd call it a housecoat) was something Joan wore for comfort while rehearsing. We've seen Grayson's smocks many times but this is the first glimpse I've ever seen of what Joan wore for this. Great photos.
All the photos say Getty Archive and presumably can be viewed if one searches DS on their site. It's incredible some of the things that have turned up there in the past couple of years.
Today was a day of sorrow and mourning ... FORTY FIVE YEARS AGO. How the hell did THAT happen??
