A priest has stunned wedding guests at the end of a ceremony with a pitch-perfect version of Leonard Cohen's Hallelujah.
The video of Fr Ray Kelly's unique version of the often-covered song was filmed at the weekend and has been watched on YouTube more than 2.7 million times in the space of four days.
The parish priest of Oldcastle, County Meath, told BBC Radio Ulster's Talkback programme that the couple had no idea what was going to happen.
"Normally local people know I sing at weddings, funerals or when I'm asked, but they didn't know - the bride Leah is from Dublin and the groom Chris is from Cookstown in County Tyrone," he said.
"They were having their reception at a hotel about 10 miles away and chose our church.
"We had the rehearsal on Thursday evening and at the end I said, 'sure maybe I'll sing an aul song for you myself' - Leah grinned and said 'OK sure' but I don't think she was taking it too seriously."
Fr Kelly changed the original lyrics to be more suitable for a wedding. It begins: "We join together here today, to help two people on their way."
The video was filmed by a company owned by County Tyrone man Patrick Rushe, who said he was amazed by the reception it has received online.
He said he was just as surprised as anyone in the church when the priest began singing the song.
"The band Sunlight who had been doing the music for the wedding had just finished singing when he put on the backing track, but people were still looking at them as they didn't know where the music was coming from - they were shaking their heads and saying it wasn't them.
"At the end of the song he got a standing ovation.
"The couple are on their way to Mexico for their honeymoon but I sent them the link and they know it has been really popular," he said.
"Chris says it's madness while Leah says her dad is freaking out, in a good way."
Fr Kelly is a trained singer who is currently working on his third album.
"I keep saying this will be my last because this year I'm 25 years a priest - I do it to make a few bob for local charities," he said.
"I enjoy singing but I wouldn't want to do it full time - I love what I'm doing as a priest.
"The way I look at it is, it's a gift one has, and if you have a gift you use it."
