Finally, some good news coming out of Ireland. From the Catholic News Service (Dublin):
The track, also known as "Peace on Earth," was always going to be included on The Priests' third album, "Noel," but mindful of the success of the 1977 recording by Catholic crooner Bing Crosby and glam-rock star David Bowie, the clergymen thought a collaboration with another singer might provide a counterpoint to their classically trained voices.
"Our management told us Shane was available and we were delighted by the idea," Father Eugene O'Hagan, one of The Priests, told Catholic News Service.
A gifted songwriter, MacGowan, former lead singer with The Pogues and later a band named The Popes, became widely known for his alcoholic binges both on and off stage. His song "Fairytale of New York," recorded in 1987, is the Christmas song most requested and played on radio in Ireland and the United Kingdom.
