A friend of mine sold his house to Nigella Lawson and John Diamond. He said that both were lovely.
Another friend of mine used to work with the Pythons and said that all of them were lovely so I'm sorry you had a bad experience with Michael Palin, londonrach.
A friend of mine is a celebrity reporter and told me that George Clooney has the most appalling breath - as though a rat had died in a whiskey bottle.
Joanna Lumley and my dad had tea together in Bhutan. He had no idea who she was (my father wouldn't recognise a celebrity if his life depended on it) but said that she was absolutely lovely.
Another friend met Brian McCarthy (one of the men held hostage for years by Hezbollah in Lebanon) at the Chelsea Arts Club and said that he was first-rate.
Same friend said that AA Gill ( of restaurant review and shooting baboon fame) is a talented artist and not as big a jerk as his public persona.
Chris Tarrant apparently is as big a jerk as his public persona.
Ran into Tina Turner years ago (just before her big comeback) and she was ok. She was wearing dungarees and had her hair scraped back, ie no wig, but she was instantly recognisable.
Rowan Atkinson is very unpleasant.
