The Tommy Tiernan Show is returning for its third run on RTÉ One this May and will now air on Saturday nights.

The third season of the unique chat show is back on Saturday May 4 and will run for eight weeks.

The show's unusual format sees Tiernan and the live studio audience kept in the dark about the guests until they walk on set, which has resulted in some memorable chats and water cooler moments.

Speaking ahead of the return of the show, the Navan comedian said: "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.

"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 its a conversation without a safety net."

Justin Healy, Executive Producer RTÉ Comedy Commissioning added: "We are very excited to bring Tommy's unique take on the chat show to Saturday nights on RTÉ One. Tommy has a way of connecting with people instantly, a skill which is a joy to watch.

"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. 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."
