Eager couples from the U.S., Croatia, Poland and as far as Japan have asked the Catholic priest of 25 years to sing at their weddings. The Irish priest's face hit the big screen at Times Square in New York this week, and an Australian TV station is sending a film crew to cover his story once his Easter duties are complete.
