Ireland's Eurovision hopeful Ryan O'Shaughnessy has told RTÉ Entertainment how Paul Harrington and Charlie McGettigan's iconic Eurovision winning song Rock 'n' Roll Kids is one of his favourite songs of all time.

The 25-year-old singer, who is set to represent Ireland at the Eurovision semi-finals in Lisbon next month, teamed up with the talented duo to perform a special rendition of their hit song on The Ray D'Arcy Show on RTÉ Radio 1 on Thursday.

Speaking to RTÉ Entertainment, the former Fair City star said that the hit track, which won the Eurovision Song Contest for Ireland in 1994, has always held a special place in his heart.

"It's always been a favourite of mine. As songs go it has always stood out. I actually had a moment with my girlfriend about six months ago when it came on the radio and we both said at the same time 'this is my favourite song'. We hadn't discussed that before.

"It's a re-occurring thing for me, and today of course, is a nice opportunity for me to meet the pair of you," he added.

Charlie McGettigan praised O'Shaughnessy for picking up the harmonies quickly and finding a nice middle ground between all of the voices.

"We've been doing a little bit of rehearsal because we're going to sing this on the radio together. We literally met and within five minutes he had it sussed and he found a harmony in between us. It's just magic when that happens," he said.

Paul Harrington said he thinks O'Shaughnessy has a "great song" in Together and admits he loves the "whole spontaneity of the video" which sees two guys dancing around Temple Bar in Dublin.

"The beauty of this is, this to me, just looks like two guys or two friends having a bit of fun in Temple Bar. And they were sober," he laughed.

The Eurovision Song Contest semi-finals take place in Lisbon, Portugal on Tuesday May 8 and Thursday May 10 with the grand final taking place on Saturday May 12.
