Wham! star Andrew Ridgeley heads the guest list on The Ray D'Arcy Show this Saturday night on RTÉ One.
The 56-year-old joins Ray to talk about his lifelong friendship with George Michael, his partner in pop duo Wham! until they split in 1986 after five years of stardom.
He'll give the inside story on how the legendary pair changed 1980s' music and became one of the biggest bands in pop music history.
Anna Geary and Mairead Ronan will also join Ray ahead of the return of Ireland's Fittest Family to screens this Sunday.
From growing up in rural Ardboe to joining the London Literati, Polly Devlin tells Ray about interviewing some of the most famous people in the world, from Bob Dylan, to John Lennon and Yoko Ono.
For the second year running, Ray is hosting Ireland's Next Top Madra, which is on the hunt to find the country's prettiest pooches. Ray will have eight of the four-legged finalists in studio on Saturday night.
And finally, 240 singers and musicians join Ray for a special performance of Hey Day by Mic Christopher in honour of the late star's 50th Birthday.
The Ray D'Arcy Show Saturday October 26 at 9.45 pm on RTÉ One
