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 the programme but said that there's "got to be an agonising reappraisal" and that Lyttelton was the "very hub of the show". Cryer, Tim Brooke-Taylor and Graeme Garden all ruled themselves out as hosts: Cryer did not think the programme would work if a panellist became chairman and it "would need somebody of stature to be parachuted in". Jeremy Hardy also ruled himself out, saying "Humph had big shoes to fill and I wouldn't do it."
