Tommy Tiernan has told fans he will once again be working "without a safety net" when his acclaimed talk show returns to RTÉ One this Saturday for an eight-week run.

Now in its third season, The Tommy Tiernan Show sees the actor and comedian back in the studio - once again with no idea of who his guests are going to be on the night.

Previous series have seen memorable, unprepared interviews with the likes of model Vogue Williams, Aslan singer Christy Dignam, Catastrophe writer and star Sharon Horgan and actor John Connors - all available to watch on the RTÉ Player.

Vogue Williams was among the guests in series one

"The chat show is unusual in the way that it creates a space where anything can happen, and I feel very lucky to be in the hands of such wonderful researchers, who really are the people that put the whole thing together," said Tiernan. 

"I just turn up and talk; they're the ones who curate it. The guests, as well, show a remarkable amount of generosity in agreeing to do it with me, because it's a conversation without a safety net."

Justin Healy, Head of RTÉ Comedy, said the presenter has "a way of connecting with people instantly".

"To have a host completely in the dark as to who is going to walk on to the set is a gamble that only Tommy could pull off," Healy continued. 

"From internationally known stars to lesser known faces, Tommy gets them to reveal an awful lot of themselves, which at times is compelling and at times uncomfortable, but always engaging. 

"Tommy is unprepared for this show in the best way possible."
