Who are Sid and Nancy?

Sid Vicious and Nancy Spungen are known for being one of the most iconic and recognisable couples in rock music.

In February 1977, Sid was nominated to replace Glen Matlock as bassist of the Sex Pistols and rose to fame as part of the band.

On October 11th 1978 during a party in the couple’s hotel room, Sid Vicious swallowed about 30 tablets of Tuinal. The next morning, 20 year-old Nancy was found dead in the room.

Whilst awaiting trial for her murder months later, Sid Vicious died from an overdose. The official Sex Pistols website reads:

“Sid Vicious’ destructive relationship with his junkie girlfriend Nancy Spungen finally hit rock bottom on October 12th, 1978, when she was found murdered in their New York hotel room. Sid was the main suspect. Whether he did it or not is still highly debatable…”
