The guest list for Saturday night's Ray D'Arcy Show has been revealed - and it includes PJ Gallagher, Katherine Lynch and Alison Hammond.
Comedians and actors Gallagher and Lynch will be chatting to Ray about their dark comedy play Madhouse.
This Morning star Alison Hammond will be making her first ever Irish chat show appearance to talk about Big Brother and interviewing Hollywood A-listers.
Singer Brian Kennedy will join Ray to celebrate his recent cancer free diagnosis and share some of his most loved songs.
On Saturday, comedian Andrew Maxwell will lead up to a million protesters in a march in London to call for a Brexit referendum. He'll join Ray in studio to explain how he got involved and why it's still a laughing matter.
And Athlone Jockey Paddy Merrigan joins Ray to talk about his rise to the top of his game, his downward spiral into drink, drugs and gambling and the turning point that led him to return to horse-racing and spread his message of positive mental health.
Watch The Ray D'Arcy Show on Saturday October 19 at 9.55pm on RTÉ One.
