Those in attendance at Christmas carol service in Sri Lanka earlier this month received a surprise when they were mistakenly given lyrics to a Tupac song.

Organisers of Joy to the World 2016 accidentally printed out the words to the rapper's 'Hail Mary' instead of the traditional Christian prayer of the same name. The track features lyrics like 'I ain't a killer but don't push me/Revenge is like the sweetest joy next to getting pussy'.

Andrew Choksy, who was at the event, is quoted as saying that some attendees were left bemused by the mistake. He said: "A lot of people around us were in shock as to whether it was a joke, or if someone would actually rap the song. A few of the older ladies in front of us could not stop looking at the printed booklet.

“No explanation was given [by organisers] at all. They didn’t acknowledge it at the venue. To be honest, I don’t think many people saw the booklet at all. The people that realised were shocked at first but then took it in good humour around me. To be honest, I was bursting inside."
