Hey!
This will be airing tonight at 9PM EST on my local NYC PSB/Thirteen channel.
https://www.pbs.org/video/robert-shaw-man-of-many-voices-asy3kh/ Check your local PBS channel for airing time. And don't worry if you missed it tonight, it will be on PBS site and you can watch it online for a limited time until you need to sign up to view it.
