Ronan Keating is to join the cast of West End musical Once.

The singer will play the part of Irish busker Guy in the production from November 17 until March 21, 2015.

The show takes place at London's Phoenix Theatre and it is based on the 2007 film of the same name, which focuses on Guy and a Czech woman meeting through music.

Speaking about his new role, Keating said in a statement: "I was truly bowled over when I first saw Once. The music and storyline are so incredibly moving and, combined with John Tiffany's direction, I believe it's a modern-day masterpiece. It's unlike anything else I've ever seen. 

"When I was asked about playing the lead male (who is a busker in Dublin) I was completely overwhelmed because I knew it would be perfect - this was my home town, my people, and the place where I began my own music career. But as exciting as that is, it's scary too."

The Boyzone man added: "I've never performed on the West End and this is a huge challenge and commitment. I'm really looking forward to returning to London later this year and completely sinking my teeth into the role. I think there's going to be lots to learn and lots to gain from this experience and I just want to be the absolute best that I can be."
