If your cable or satellite receives The Biography Channel…and if you're a fan of Sesame Street and/or the Muppets, you might want to set your TiVo or VCR for the wee small hours of next Saturday morn. They're rerunning a two-part "Biography for Kids" that Harry Smith did, visiting the set and interviewing the folks behind, in and under the Muppets. Special attention is given to Kevin Clash (who performs the role of Elmo), Carroll Spinney (who plays Big Bird and Oscar) and Steve Whitmire (who took over the roles of Kermit and Ernie after the death of Jim Henson). It's a really good look at how the show is made. Part One airs at 4:00 AM on my satellite dish with Part Two following at 5:00 AM. Your time zone or cable company may differ.
