I have seen Iris live several times, including on “The Mountain Stage”. One of those appearances was when I took my mother and a family friend to the show, about 4 hours from my home.
One of the songs done that evening was an excellent version of “The Long Black Veil” everyone did to close the show. I have checked from time-to-time to get that song, as it was not a part of the broadcast version.
Recently, I went to the official web site and discovered their podcast Digital Archives Project; an effort to make available over 800 shows in digital format. They are releasing the shows on podcast and need additional help in funding the project. I sent them a small donation for the project and I encourage you to also contribute.
