Here's Judy...not in the best physical shape, but her wit completely intact. She's so quick you sometimes miss the funny things she's saying. About 10 minutes in, she tells a hilarious story about submissions from a amateur songwriter.
This was Cavett's brief 1968 ABC daytime show before his late-night show. When this one aired, it had already been canceled and this was among the last few installments, hence the reference to the curtains Judy admires being "available" soon.
This seems to have been taped off the air in 1968 using very primitive technology. The audio portion gets "scratchy" on occasion because the broadcast signal, probably on a TV set using rabbit ears, was being distorted.
Poor Judy was on her last legs, worn down by the business end of "the biz", as she calls it.
