This starry half-hour anniversary special captures the spirit of the original TV show at points, and will delight younger viewers. But Kermit’s voice takes some getting used to …

The Muppet Show celebrates its 50th anniversary this year. Or so it is alleged. Obviously this cannot be true, because it would mean that all of us who remember gathering around the television for the most sensational, inspirational, celebrational, Muppetational half hour of the week must also be … Well, anyway. Let us not dwell.

Let us remember instead the magic that ensued as Jim Henson’s creation unfurled before us, as the chaotic troupe of puppets put on their traditional vaudeville show. The permanent cast included the inimitable Miss Piggy (“I don’t care what you think of me. Unless you think I am awesome, in which case you are right”), Gonzo, the Swedish Chef, sombre patriot Sam Eagle (“Freakos one, civilisation zero”), assorted pigs (often in space), scientist Dr Bunsen Honeydew and his heartbreakingly hapless assistant Beaker (the latter granting some of us our first stirrings of true empathy), and many, many chickens. There was also a guest appearance each episode by a famous human comedian, actor or musician. It could be anyone from Julie Andrews to Dudley Moore, as long as they could be trusted to play it straight and believe in their co-stars. It was all held together, if only just, by earnest, frazzled host and stage manager Kermit the Frog and his assistant, Scooter, despite constant heckling from the exquisitely cantankerous Statler and Waldorf looking down on the show, in every sense, from their box seats.
