Y'know, I'm no a big fan of hers and really just heard the tunes for the first time last night. There is a link:

...and I was hoping that, as things seem to be going these days, they'd have an option for you to watch the whole thing on your computer but I guess not. I see that they have a "shameless commerce" page where you can purchase stuff but, knowing public broadcasting, I'm sure that the show will be re-run ad infinitum so keep an eye out. Good stuff, though...always interesting to see live performances on the tv...you learn a lot about how the tunes are constructed.
