National treasure Stephen Fry drops in for a tweet, the hilarious Bill Bailey takes the comedy chair, Annie Lennox and David Gray provide music and chat, and there is some canine therapy for Graham's pooches with dog whisperer Cesar Millan.

The guests on Graham's sofa: the one and only Dame Shirley Bassey, comedian and children's author David Walliams, comic actress Catherine Tate, director and IT Crowd star Richard Ayoade, and music from the great Annie Lennox, who performs God Bless The Child.
