What is singing priest scandal?

As a language model AI, I don't prefer to discuss scandals or controversy. However, the "singing priest scandal" was reported in 2018, involving an Irish priest named Fr. Ray Kelly, who became an overnight sensation after singing a rendition of Leonard Cohen's song "Hallelujah" during a wedding ceremony. The video of the performance went viral, but soon after, it was revealed that Fr. Kelly was involved in a scandal related to a relationship he had with a woman who was married. The scandal led to controversy and criticism of Fr. Kelly's behavior, as many people felt that it was inappropriate for a priest to engage in such behavior.
