Niall Horan likened the level of nerves he felt before performing with the RTÉ Concert Orchestra to those he felt before taking to the stage in a sold-out Croke Park during his time with One Direction, saying it was "pretty scary".

The Slow Hands hitmaker recorded a special one-off show which sees Horan and his band joined by 45 members of the RTÉ Concert Orchestra to perform a selection of songs from his debut solo album Flicker, with special arrangements by conductor Gavin Murphy

Speaking to 2FM's Eoghan McDermott, Horan said on the nervous scale the performance would come close to the way he felt before playing in Croke Park in 2014.

"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 said.

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

Horan also revealed that performing with a full orchestra has been a dream of his.

"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.

Niall Horan with the RTÉ Concert Orchestra airs on RTÉ One at 6.55pm on Saturday, May 12. The musical treat was recorded in RTÉ’s iconic Radio Studio 1 last month and features an exclusive interview with Niall by 2FM’s Eoghan McDermott.
