Glen Hansard said he saw taking part in a voyage rowing from Ireland to Santiago de Compostela as a chance to "reconnect into Ireland."
Camino Voyage is a documentary that follows the 2,500km voyage undertaken by writer and poet Danny Sheehy, singer Glen Hansard, musician Brendan Begley, artist Liam Holden and stonemason Brendan Moriarty from Ireland in a traditional Irish currach boat, all the way to Northern Spain.
Hansard joined Ryan Tubridy on Friday's Late Late Show to talk about his experiences at sea and described it as a way of getting back in touch with his roots.
"For me what was so amazing about the opportunity to do it was that over the last 10 years or so of my life, I've spent a lot of time travelling, I've spent a lot of time out of Ireland," Hansard said.
"I think in a way you become unstuck with your land, with your place, with your home place. Don't get me wrong, I'm not into flag waving, but that sense of Ireland.
"I think when you send out a message in your head that goes 'I'd love to reconnect into Ireland' what a great opportunity to go on a boat with a bunch of Gaeilgeoirs and to be around the language and the spirit of these Kerrymen rowing this boat and to be on the sea."
Camino Voyage is released next Friday, November 23.
