Shimmying into Graham's studio tonight is Hayden Panettiere, one-time self-mending heroine of cult US sci-fi drama Heroes, now strutting her diamanté chic in slick US country soap Nashville. Also dropping in for a chat is Dan Stevens, Downton Abbey's Matthew Crawley - one of the few decent chaps in the period drama - who was controversially bumped off on Christmas Day. Just after he'd become a new dad, too. Such a harsh way to write out a character. The nation was not amused as we choked on our figgy pudding.
