Sex Pistols frontman John Lydon has said being in the band was "hell on earth" and has hit out at his bandmates for "doing the dirty’ on him with new biopic series Pistol.

Lydon – known as Johnny Rotten during the Sex Pistols’ heyday – has been embroiled in a public feud with the remaining members of the group over the upcoming drama.

After losing a court case against his bandmates earlier this year to stop them using his music for the project, Lydon has reflected on his time in the band and claims his experience was far from the "glory days" most assume.

“I don’t know that there was much glory. It was mostly hell on earth,” he told Metro.

“There was constant pressure but I got to write the songs I wanted to write, got those lyrics out to Joe Public and Joe Public was very nice and appreciated it.

“But then I had a media and a police force who did not appreciate it. I was discussed in the Houses of Parliament under the treason act.”

Lydon said the court case put him in a “financial hole” but that he was “resilient”, and claimed that rather than refusing the music for Pistol, he wanted to know more about the project but was denied access.

He said: “They did the dirty on me. For three years his project was going to exclude me,” he said.

“I only found out in January and they took me to court a month and a bit later under the guise that I denied them access to the songs.

“I denied nothing. All I did was ask what was going on and to this day I’ve received no information at all.”

He also criticised filmmaker Danny Boyle for his involvement in the project and for excluding him.

In response to his comments, a spokesman for the series told the paper: “John Lydon sold his rights to control the use of these songs in the 1990s in return for money.

“The majority rule agreement existed as a result – so no outside party could dictate the use of the band’s music. And to have a mechanism in place if one member was unfairly blocking the decision-making process – which is what happened in this instance.”

Pistol is based on the memoir Lonely Boy: Tales From A Sex Pistol by guitarist Steve Jones.

The six-episode mini-series was ordered by US network FX, and stars Anson Boon as Johnny Rotten, Louis Partridge as Sid Vicious, Toby Wallace as Jones and Jacob Slater as Paul Cook.

Maisie Williams is also set to appear as fashion icon Pamela Cooke, with Emma Appleton as Nancy Spungen.

Pistols has not yet been given a release date.
