HE played a bit of Michael Buble, discussed Good Friday and what would happen if you press the big red button. As it happened, it turned out to be the bell for the Angelus.
It might have been his first time to sit in the hot seat but 'Moone Boy' star Simon Delaney took to it like a duck to water – albeit a very curious one.
He could not wait to feel his way around the unfamiliar controls of the RTE radio centre.
Filling in for Ryan Tubridy on RTE 2fm – who will spend his Easter holidays deputising on BBC radio Simon Mayo's drive-time show – Delaney appeared excited as the show began.
He told listeners that what he was looking forward to most over the course of the programme and next week – was taking their calls and talking about whatever they wanted to discuss.
In a tweet the night before, the actor – who will soon be seen in Hollywood comedy 'The Delivery Man' alongside Vince Vaughan – said: "Thx for all the good luck msgs for 2moro, means a lot! Nervous, but no doubt you'll all be phoning, texting & e-mailing in, right?!"
After the show, he said he had "a blast", adding: "Roll on next week!! Now, 2 wins for Utd over the weekend would be lovely!!"
A spokesperson for 'The Tubridy Show' said they were very happy with how it had gone and said it had been "fun".
Delaney attended a production meeting after coming off air but did not hang around afterwards. A member of the 'Tubridy' team explained: "He's a very busy man."
Broadcaster Craig Doyle has filled in for Tubridy on previous occasions but this is the first time RTE has called on the IFTA host to take the helm.
The actor is best known for his portrayal of solicitor Michael Quinn in 'Bachelors Walk' but has been slowly but steadily hitting the big time.
In his biggest role to date, he plays a New Yorker delivery man whose brother has just found out that he has fathered 533 children as a sperm donor.
