BBC Radio's multi award-winning antidote to panel games starts its first live tour in 35 years.

Join Humphrey Lyttelton, Barry Cryer, Graeme Garden, Tim Brooke-Taylor, Jeremy Hardy and pianist Colin Sell for an unmissable evening of inspired nonsense.

I'm Sorry I Haven't a Clue, sometimes abbreviated to ISIHAC or simply Clue, is a BBC radio comedy which has run since April 11 1972. Since then, the programme has had several series each year, being broadcast on BBC Radio 4, BBC 7 and the BBC's World Service.

The show, introduced as "the antidote to panel games", consists of a panel of four comedians, split into two teams and "given silly things to do" by a chairman.

The show was conceived as a parody of the then-ubiquitous radio panel game, and includes elements that satirise such shows, both on radio and television.

Guest panellists who have appeared on the show include Bill Bailey, Max Boyce, Rob Brydon, John Cleese (who was a regular panel member during the first series in 1972), Jack Dee, Kenny Everett, Stephen Fry, Tony Hawks, Harry Hill, Jo Kendall (another regular panel member during the first series in 1972), Paul Merton, Linda Smith and Sandi Toksvig.

"Whether the teams are singing the words of one song to the tune of another, making up serial rhymes or entering the mythic maze of Mornington Crescent, they have now become the National Theatre of fun." Gillian Reynolds, Daily Telegraph.
