A warm Yuletide special, A Muppet Family Christmas pairs the Muppet gang with the perennial favorite Sesame Street cast for a holiday celebration. With a blizzard brewing outside, Fozzie's childhood farmhouse on Christmas Eve becomes the backdrop for a medley of holiday tunes--eight in all--ranging from the Muppet band's rousing "Jingle Bell Rock" to Big Bird's sweet rendition of "The Christmas Song." Though the script meanders in part, the 42-minute program shines as a musical revue, seasoned with quick-witted interludes by the culinary comedic Swedish Chef, slapstick odd couple Ernie and Bert, and the diva-like escapades of Miss Piggy. While lacking the irresistible sizzle of The Muppet Movie, the show's finale, which includes Kermit and Piggy under the mistletoe and a cameo appearance by Jim Henson, proves that nothing can dim the Muppets' appeal. --Lynn Gibson
