The Rev. Eugene O'Hagen, 48, his brother the Rev. Martin O'Hagen, 45, and their friend the Rev. David Delargy, 44, collectively called "The Priests," signed their contract Wednesday at London's Westminster Cathedral, The Times of London reported.
"They're going to be wonderful global superstars," said Nick Raphael, managing director of Epic Records of Sony BMG.
The priests, who all have parishes in the Northern Ireland diocese of Down and Connor, said their music earnings would be donated to charity, the newspaper said.
The trio made sure to leave a special stipulation in their deal with Sony that permits them to take time off the music business to handle parish duties, the Times reported.
"We are priests first and foremost. Our work will be at the heart of our plans," Martin told the Times.
The Priest's new record reportedly is set for a November release.
