X Factor judge Louis Walsh has said that Ireland must "stick at" the Eurovision despite our recent semi-final disappointments in the song contest.

Walsh was among Miriam O'Callaghan's guests on Saturday Night with Miriam where he admitted that he is still none the wiser as to why Ireland failed to qualify for this year's final in Ukraine with Galway man Brendan Murray singing Dying to Try.

"He sang so well," said Walsh. "I chose the song and the singer... I thought he was going to sail through."

Asked by O'Callaghan how Ireland could win the Eurovision again, Walsh replied: "By just sticking at it. I picked a ballad this year because we always won with ballads - Johnny Logan and Linda [Martin] and Niamh Kavanagh and stuff. So, I thought we were going to do really, really well. I still think RTÉ should do it."

Walsh said that while trying to find Ireland's Eurovision entry he contacted lots of well-known songwriters but "they didn't want to know".

"And some of the singers they don't want to touch it because they're afraid of not doing well at it," he continued. 

When O'Callaghan inquired if that is a problem unique to Ireland, Walsh answered: "It's everywhere, but I still think we should stick at it."

Walsh went on to pay tribute to young Irish performers, adding that radio needs to do more to develop homegrown artists.

"We have the talent here; we just need to encourage it," he said.
