Just watched this with guest chef Galton Blackiston. The way James Martin was talking to him I found uncomfortable to watch. He was winding Galton up and taking the pee out of him. Galton looked like he didn't want to be there.
Didn't see him today but have seen him several times on the BBC's Saturday Kitchen and he always looked shy and awkward. I don't think he's very comfortable in front of the cameras.
