"The Muppets Holding Company has revealed that "The Muppets' Wizard of Oz" will air in the United States on Friday, May 20, 2005 at 8:00 pm EST on ABC (check local listings for full details). The film's debut will be a two-hour television event (the film itself running 88-minuets, plus commercials and ads). ... The premiere should be an uplifting and encouraging experience for Muppet fans, as the Monday prior (May 16) will mark the 15th anniversary of the death of Muppet-creator Jim Henson."
Now, if I could just find an MP3 of the Doozer Knitting Song! (from a Fraggle Rock episode called "The Great Radish Famine")
