Ronan Keating is about to take to the West End stage and admits that he's suffering from some pre-show jitters.
The Boyzone singer will make his West End debut later this month, starring as Guy in the musical version of Once - the popular film. He follows on from the likes of EastEnders' Declan Bennett and Doctor Who star Arthur Darvill.
"It's really scary to be honest, because I guess there's a lot expected of me," he said.
"I'm really looking forward to it. I have a lot of other work to do with guitar-playing and acting and singing and all that. So we'll see how it goes. I'm excited."
Speaking about swapping a concert for a musical, he added: "To be honest, I actually never thought I would do the West End, but it's this role that excited me and made me want to do it. It has great dialogue, great direction and great songs.
"It's not really a musical it's more like a play with great songs," he added.
Ronan (37), who is engaged to Australian beauty Storm Uechtritz, believes Once is still so popular because it has so many different elements to it.
"From the moment that the audience are allowed to step onstage and actually have a beer on the set, that is incredibly unique," he told Digital Spy. So from that moment on to the ensemble being the band, rather than a band in the pit, to this great dialogue and the humour and then the songs. It's so layered, there are so many elements."
Keating also revealed that he may plan to release studio versions of the musical's songs.
"There might be live recordings along the way. I don't really know what the plan will be right now."
