We know what we'll be watching later.

None other than Michael Gambon, who played Dumbledore in the Harry Potter films, will be on The Late Late Show tonight. The Dublin-born actor will soon take to the stage at The Gate Theatre. He’ll be chatting to Ryan about his extraordinary career alongside Michael Colgan, The Gate’s artistic director. Actor and writer Emmet Kirwan will also be on the show. His powerful take on the state of the nation, ‘Heartbreak’, went viral earlier this year. Kirwan will be chatting about striking a chord with his latest work and where he thinks Ireland is at right now. Nathan Carter's younger brother will make his television debut tonight. Hot on the heels of his brother's success, he has a brand new song, Trouble, that he will perform on the show. Rosemary Adaser will tell Ryan and the audience about her life and what life was like to grow up in Ireland in the 1950s. When she became pregnant at 16, the baby’s father wanted to marry her but she was sent to a mother-and-baby home and her child was taken away from her. Rosemary will tell her story on The Late Late Show, alongside Brian Rothery, the foster father who helped to build her back up after years of suffering. Professor Sabina Brennan will be talking about how Ireland is with the topic of aging and a panel, including Mary O’Rourke, George Hook and Rita Ann Higgins, will be telling the viewers about their experiences of life after getting the bus passes. More music on the night will come from Brian Kennedy.
