It's a Sin

It's a Sin is the tile of a song written and recorded by British duo Pet Shop Boys, released as a single on 15 June 1987. It became their second number 1 and was the lead track to their new album Actually, released in September.

"On June 15th 'It's a sin', a song that originally appeared on the demo Neil had in his pocket when he took Bobby O' out to lunch, is released. 'It's about being brought up as a Catholic. When I went to school you were taught that everything was a sin'. It reaches #1 and causes several notable rumpuses. Jonathan King accuses them of plagiarism (he later apologizes and pays damages to a charity at their request). A teacher at Neil's old school, St. Cuthbert's Grammar School, Newcastle, gets very steamed up about the picture Neil has seemingly painted of his education and castigates Neil in the press. The Salvation Army magazine, War Cry, put the Pet Shop Boys on the front page and note, approvingly, 'It's interesting that someone's raised the concept of sin in our modern life again'. Neil is also asked to appear with Cardinal Hume in a press advert for CAFOD; he politely declines the offer, explaining that he isn't a practising Catholic. The song's video, a sombre tale of guilt and punishment featuring the seven deadly sins, was the first time the Pet Shop Boys work with Derek Jarman."
