Irish star Niall Horan's collaboration with the RTE Concert Orchestra was a resounding success.

The one-off special performance saw the Mullingar native joined by 45 members of the RTÉ Concert Orchestra and conductor Gavin Murphy.

Ahead of the performance, which was recorded last month, the 24-year-old singer/songwriter sat with friend and host Eoghan McDermott to talk about his stellar career.

Horan likened the pre-performance nerves with the renowned orchestra to those he felt before taking to the stage at a sold-out stadium gig. In particular, his 2014 show with former One Direction bandmates in Croke Park.

"Pretty close to Croker, first of all it's on home soil so it's pretty scary anyway, it's going to be seen by everyone I know and people I don't know obviously," he told McDermott.

"It's my first time playing with musicians at this level, I've only ever played with quartets here and there, so  for RTE to give me the house orchestra is pretty special."

"It's something that obviously everyone wants to do, something that I've wanted to do all my life...proper musicians, all 45 of them, it's just going to be epic," he said.
