Father Ray Kelly take to the Britain's Got Talent stage this evening, vying for a place in Saturday night's final.
The 64 year old priest in Oldcastle, Co. Meath impressed the judges when he sang REM's Everybody Hurts in the first round of the contest.
Simon Cowell said that Fr. Ray's audition was one of his "favourite ever auditions."
Fr. Ray hasn't revealed what song he will sing on tonight's semi-final, but has said that it will be a tribute to his late sister Regina McMahon.
Regina passed away from oesophageal cancer in 2016 at the age of just 59, and Fr Kelly says he learned the song shortly after her death.
Friday night's semi-final begins on TV3 and ITV at 7:30pm, with the final taking place on Sunday June 3, also at 7:30pm.
