HappyKT found a recording she made of Lucy's tv appearance during her Chicago 2007 concert promo on the WGN Morning News in Chicago on 4 October 2007.
I delved into the archives and this is what was posted October 2007 - unfortunately the video from the site has long since disappeared (that is why you need to save videos and images from the original source and keep them because they will disappear as new material is added to sites that don't normally archive their content. Found it? Download it immediately).
