Questions from the audience inevitably focused on Monty and had nothing to do with the guest whom he was interviewing. What do you think of the Chelsea judging row? What row. Would you like to know about my vegetable company? No I would not. What about slugs, Monty?
"I've never been anywhere without someone asking me about slugs," said Monty, not without humour. But the question did not go away. What about Lucy, what does she do about slugs, he asked?
"Me? Slugs? Nothing really..." she trailed off.
A national collection of hostas is held at Prince Charles' organic garden, Highgrove, by way of slight digression. They are proud specimens, as are Monty's.
"Now can we move on from slugs please," said Monty, ever the pro. "It's almost time for lunch."
