Award-winning funnyman Alan Carr continues his fourth series of what's become one of the UK's favourite entertainment shows with its weekly fix of celebrity chat and topical banter. Last week, he tried to ply tee-totallers Bobcat and Robin Williams with booze; this week the guests are Ricky Gervais and Stephen Merchant who talk about the DVD release of their film Cemetery Junction. British actress Minnie Driver drops by to chat about her (some might say miscast) role in the new BBC drama The Deep, and former X Factor winner turned pop star Alexandra Burke gibbers excitedly about what's going on in her life and performs her new single Start without You.
