== Synopsis ==

Billed as "the antidote to panel games", ISIHAC (as its lazier fans call it) has become a radio institution. 

Originally devised as a way for the cast of the sketch show ''I'm Sorry I'll Read That Again'' to show off their comic talents without having to go through all that time-consuming business of writing and rehearsing beforehand, ISIHAC has stood outside the whims of fashion for more than thirty years and has become the  longest-running improvisational comedy show on the radio. Or anywhere else, for that matter.

The original panellists were ISIRTA regulars Tim Brooke-Taylor, Graeme Garden, Bill Oddie and Jo Kendall, with Humphrey Lyttelton and Barry Cryer alternating as chairman. Kendall left after one series, whereupon Cryer took up a permanent place on the panel and Humph became full-time chairman. The classic line-up was completed shortly afterwards, when Oddie left to be replaced by Willie Rushton. There were occasional substitutions over the years when one of the regulars was otherwise engaged (John Cleese was a frequent stand-in in the early years, and later Bill Tidy) but essentially the line-up remained unchanged until the sudden death of Rushton in 1996, since when it's usually been the three regulars plus guest.

The players are given, as the end credits put it, "silly things to do". Among the classic games are ''Cheddar Gorge'' (basically the old kids' game of adding words to a sentence one at a time), ''One Song To The Tune Of Another'' (the very first game ever played on the programme, and pretty self-explanatory; one of the series' running jokes is Humph's needlessly complicated explanations of this game), ''Limericks'' (again, pretty easy to grasp), ''Sound Charades'' (charades using, er, sound - generally involving a pun on the title to be guessed) and ''Mornington Crescent'' (a supposedly tactical - but actually nonsense - game which has spun-off into at least two books and a spoof documentary).

Overseeing all this is Humphrey Lyttelton. Apparently chosen because of some half-baked notion about the game being "like jazz" (no, us neither), his weary, yet impeccably timed, delivery is certainly one of the best things about the show. He has his own set of running gags - mock letters from a "Mrs Trellis of North Wales", frequent insinuations that the show's (excellent) pianist, Colin Sell, is actually rubbish, and references to "our lovely scorer, Samantha", with ever more contrived double-entendres about what she gets up to during the games. (Legend has it that some of Radio 4's less well-attuned listeners have been known to write in complaining about the treatment supposedly handed out to the - obviously - non-existent young lady. Who'd be in her fifties by now, anyway.)

== Catchphrases ==

"I have a letter from a Mrs. Trellis of North Wales..." (and variations)

==Inventor==

[[Graeme Garden]], David Hatch and [[Bill Oddie]]<!--The BBC site says Garden, Hatch and Oddie. Roger Wilmut's book "From Fringe To Flying Circus" quotes Garden saying that he and Hatch devised the format, no mention of Oddie.-->

== Trivia ==

The "mystery voice" which provides the ''Sound Charades'' answer to listeners at home is a reference to an earlier "mystery voice" (actually Norman Hackforth) who appeared on [[Twenty Questions]].

== Theme music ==

Composed by Ron Goodwin (with a bit by Hadyn), originally from the 1969 film ''Monte Carlo or Bust!''.
