Olivia Tracey, former Miss Ireland and hostess on high-tech 80s gameshow Murphy's Micro Quiz M, is among the guests on tomorrow's night's Saturday Night Show.

Olivia was the main attraction on the Sunday night quiz which saw families clash for prizes against a dazzling backdrop of state of the art computer graphics, all under the twinkling eye of host Mike Murphy. OK, it made Quicksilver look like The Krypton Factor.

Olivia, who represented Ireland in the 1984 Miss Universe compeition, now lives in LA where she works as an actor and she'll be talking to Brendan about life in la-la land.

Also on tomorrow night's show, which airs at 9.35pm on RTÉ One, Limerick-based guitar prodigy Andreas Varady, who has been signed up by Quincy Jones, talks about mixing with Hollywood legends, playing with some of most influential recording artists in the world and finding time to go to school. Andreas is just 15 years old.

Also joining Brendan is Mark Hederman, the Abbott of Glenstal Abbey. He’ll be telling Brendan how he reluctantly became a priest and talks life, love and why he thinks the Catholic Church is a dinosaur.

Former Cork Butcher Pat Phelan, who lost everything to alcohol addiction, talks about how he rebooted his life, launched a tech startup and now looks set to be one of our most successful tech entrepreneurs.
