They outraged the nation with their four-letter outburst on teatime television - but former Sex Pistol Glen Matlock now says he disapproves of swearing.
The band’s bassist claims repeated use of the f-word is “pathetic”.
Now a respectable family man, Matlock does not like his children, aged 11 and seven, hearing obscenities on the radio or TV.
“It’s pathetic when people just swear for the sake of it,” the 48-year-old tells a Channel 4 show this Sunday. “Something ought to be done about it.”
His words may come as a surprise to fans of the punk rockers who will go down in history for their appearance on Bill Grundy’s Thames Today programme in 1976.
When lead singer Johnny Rotten muttered a swear word under his breath, a worse-for-wear Grundy goaded the band members to “say something outrageous”.
The band duly obliged with a volley of obscenities which outraged Britain and killed Grundy’s career.
Matlock makes his comments in X Rated: The TV Shows They Tried To Ban, which replays the infamous incident.
The bass player wrote The Sex Pistols’ three big hits – Anarchy In The UK, God Save The Queen and Pretty Vacant.
But he was replaced in 1977 by Sid Vicious, allegedly because he was a fan of the Beatles. He formed a new band, The Philistines, and regularly performs in aid of children’s charities.
