Everyone knows it, and no doubt you've even sung along to the chorus at a party - but have you ever realised how dark a song 'Delilah' actually is?
Tom Jones recorded the song over 50 years ago and it remains one of the Welsh icon's biggest hits. However, in today's modern age, its lyrics - which many argue glorify violence against women - are deemed unacceptable.
The Welsh Rugby Union removed the song from its playlists at the Principality Stadium in Cardiff back in 2015, and now visiting choirs singing at the venue have been forbidden to add 'Delilah' to their repertoire.
The lyrics of the song tell the story of a woman being murdered by a jealous partner who had been spying on her, with the second verse reading:
"At break of day when that man drove away, I was waiting
I crossed the street to her house and she opened the door
She stood there laughing
I felt the knife in my hand and she laughed no more."
A spokesman for the stadium said: "Delilah will not feature on the playlist for choirs for rugby internationals at Principality Stadium. Guest choirs have also more recently been requested not to feature the song during their pre-match performances and throughout games.
"The WRU condemns domestic violence of any kind. We have previously sought advice from subject matter experts on the issue of censoring the song and we are respectfully aware that it is problematic and upsetting to some supporters because of its subject matter."
Jones has said in the past that people took the lyrics "too literally" and denied that it trivialised violence against women.
The news has been the subject of debate on social media, with some calling it 'performative' and that banning songs is the start of a slippery slope - while others say that it is the right thing to do, given the rate of women killed by men in the UK.
Even Boy George had weighed in...
It is understood that fans will not be banned from singing the song, however.
