When the Sex Pistols released 'Never Mind the Bollocks, Here's the Sex Pistols' in 1977, it sparked off a musical and social revolution in England and became one of the landmark albums of its time. To mark the record's 35th anniversary, Universal Music UK will release a special deluxe box set version on Sept. 24.

According to the Sex Pistols' official website, the original master tapes for 'Never Mind the Bollocks, Here's the Sex Pistols' were long thought to have been lost until they were discovered recently during the move from Virgin Records to the Universal Music catalog. The tapes have been remastered for the first time ever for this collection under the direction of Chris Thomas, who produced the original album. The box set includes rarities like a demo studio recording of 'Belsen Was a Gas,' the only song from that era previously thought not to have been recorded, as well as the six demos that comprise the bootleg album 'Spunk' in their original form.

The project also features a selection of Chris Thomas' unreleased demos and outtakes from the album, including tracks with Sid Vicious on bass, as well as previously unreleased live performances from 1977, a live DVD, a hardback diary of 1977, artwork, posters, stickers and handwritten lyrics.
