Having watched him on Saturday Morning Kitchen, I would be tempted to invite the lovely Jay Blades to dinner. He has obviously had an interesting journey to get to where he is; left school basically illiterate, written off by his teachers, and now works with youngsters showing them how to refurbish, make, learn craft skills. I could ask his advice about the watermark on my dining table while he was there 
He said on tv that he had never had a story read to him as a child, isn’t that sad? Yes, he seems as if he would be a lively and pleasant dinner companion, and easy to get along with.
I would choose Paul Merton, or David Mitchell.
