I thought it was really good, and agree with the comments about the questioning, they handled it well, but then they are pro's, well done guys. 
The cooking bit was funny too, although Simon Rimmer didn't seem aware Marti is tea-total these days, but Marti handled that tactfully too by just going along with it. I was also really impressed the way Marti cracked the egg open with one hand, I can't for the life of me do that and I have been cooking for years, if I had tried that the egg would have just disintergrated and you would have had shell in the dish and the egg all over my hand, so well done to him. 
It was nice to hear Janet's mail get read out, but one thing that does annoy me about these programmes is that they encourage people to mail in with their questions, they were still asking people to mail during the show, then they don't allow enough time. I know enough fans on here to know that they would have emailed the show and it can be a bit disappointing when they just read out one. I feel they try to cram too much into these shows and it would be much more appreciated if they could concentrate on fewer guests and give them more time, it is a 90 minute programme, they could use that time better. But overall, very enjoyable seeing them on a show like this, and again well done to Janet for getting her mail read out.
Just one more thing I did notice at the end, not related to Marti and Graeme, but when they were in the kitchen, that presenter coughed into his hands, and was then immediately given the job of using his hands to spread the ingredients across the mackeral salad, not very hygenic and I am glad our boys weren't eating that dish.
