With a history of performing stretching back to their childhood, Fathers Eugene and Martin O’Hagan and David Delargy became known as The Priests when in April 2008 they signed a recording contract in front of Westminster Cathedral. The event featured in the national news, the international print media, even making the cover of Time Magazine.

Their debut album was released in 40+ countries, and earned them a place in the Guinness Book of Records as the fastest selling debut for a classical act, as well as gold and platinum discs for sales throughout Europe and Australia in addition to topping the classical Billboard chart in the US.
Their first three albums, The Priests, 2008, Harmony 2009 and Noel 2010 were each nominated as Classical Album of the Year in the Classical Brit Awards. They have performed for Popes John Paul II, Benedict XVI and Francis, as well as for the late Queen Elizabeth II and the now King and Queen Consort.

The Priests continue to serve as full time priests in the Diocese of Down and Connor in Northern Ireland. The majority of their music income goes into their charitable trust, The Priests’ Foundation, which has helped build schools in Cambodia, Uganda and Thailand, plus has helped look after retired priests, the homeless and supply schools with music apparatus. In 2020, The Priests were awarded MBEs in recognition of their contribution to Music and Charity in Northern Ireland.  In 2024, The Priests mark the 50th anniversary of their musical collaboration.
