WATCH: Wedding singer provokes furious reaction from his mother by pretending to forget song lyrics

Gerard Kelly was on route to sing at his cousins wedding when he decided to wind up his mother by pretending to not know the lyrics to a song he was due to perform.

"In A Country Churchyard" by Chris de Burgh, is a song that holds dear to his mothers heart.

"I knew the song was also her and my fathers wedding song. I was more than comfortable with it. I noticed my Mam was getting more and more stressed on the journey so I decided to have a laugh and wind her up."

The reactions from his mother are priceless.
