I'm Sorry I Haven't a Clue show's longevity. On 18 April 2008 the producer of "I'm Sorry I Haven't A Clue", Jon Naismith, announced that, owing to hospitalisation to repair an aortic aneurysm, Humphrey Lyttelton would be unable to record the scheduled shows and that they would have to be postponed. The final show of the 2008 "Best of" tour on 22 April would be presented by Rob Brydon. Following Lyttelton's death there was speculation that the series might be cancelled because replacing him would be extremely difficult if not impossible. In a eulogy in "The Guardian", Barry Cryer did not allude to the future of
I'm Sorry I Haven't a Clue on his first move, thus denying the distinguished guest the opportunity to make a single move. The chairman apologised but explained that this was an unavoidable possibility and the guest left without having uttered a word. The show was allegedly inundated with complaints at the treatment of Sir Alec Guinness as on the actual recording Lyttelton can be heard to say, "Well I'm very sorry about that. Rather unfortunate.
