I didn't notice before posting that it only addresses the 20th C.
Hopefully this will become available online or on-demand.
I did a talk 2 years ago at Greenfield village entitled "The Minstrel Show Conundrum", looking at minstrel shows across the 19th century. It is a fairly complex topic.
I just watched this show that I DVRed when it was on. Though it focuses more on the 20th than 19th C, it does discuss the 19th C and I thought it was very interesting with two historians that know their subject. I also see that it airs again in about an hour on CSPAN3. Set your DVRs if you can.
Man, I searched and searched but to no avail. I don't have CSPAN3 in my DirectTV package...ugh
Sorry you couldn't find it, Rob. A lot of people can't get CSPAN3. I'm lucky on this issue as it comes with my basic cable. Every Friday, I look for programming that airs on the weekend as it's all historical lectures, etc.
Yes, that's it. Thanks, Joel.
AWESOME, JOEL!! Thanks for posting the link. I now have something to watch on my commute...
