If you're a big Brendan O'Carroll fan you might want to cancel your plans for the evening.

The actor and comedian will be on The Late Late Show to celebrate the twentieth anniversary of his hit character Mrs Brown. Brendan will be joined by some of his Mrs Brown's Boys castmates, including Jennifer Gibney, Eilish O'Carroll and Danny O'Carroll, as he looks back on two decades of success. There'll also be a live musical performance from Mrs Brown's Boys D'Musical. Also on with Ryan tomorrow night will be Joe Duffy. He and writer Freya McClemence will be talking about their new book Children of the Troubles and some of the forgotten younger victims of the conflict in Northern Ireland. Bernard O'Shea will be on the show too. He'll be discussing masculinity, marriage and his new book, My Wife is Married to a Feckin' Eejit. With sport fans still fixated on the Rugby World Cup in Japan, Ryan will chat to former Ireland international Jamie Heaslip. Now appearing as a pundit as part of RTÉ's coverage of the tournament, he'll be previewing Saturday's clash against Samoa and reflecting on his own World Cup experiences. Speaker of the House of Commons, John Bercow, will sit down for his first ever Irish interview and singer Sibeal Ni Chasaide will be performing The Beatles's classic song Blackbird. The Late Late Show airs on RTÉ One at 9.35pm.
