Rare film footage from landmark concerts by punk trailblazers Sex Pistols will go up for auction later this month.
The sale of the video, which captures historic moments from two of the punk band's performances at Manchester’s Free Trade Hall in June and July 1976, comes shortly after a British High Court ruling over the use of Sex Pistols music in a forthcoming television series.
The June concert has been previously described as "the gig that changed the world" as it inspired a generation of Mancunian musicians who attended the performance.
The footage and its copyright will go on sale on September 14 through Omega Auctions with a price tag of upwards of £20,000.
Auctioneer Paul Fairweather said: "These concerts have entered into punk folklore and justifiably so.
"The impact that the shows had and the events they inspired truly did change the course of musical history.
"The footage shows the Pistols at their sneering, swaggering best and truly does capture what must have been so electrifying for the audiences lucky enough to have attended.
"We think they are incredibly exciting and can’t wait to see how they will go on auction day."
Members of the punk rock band Buzzcocks organised the Manchester concerts after watching the Sex Pistols play in London.
The June 4 concert had a small attendance of around 40 people but featured many artists who would go on to shape music history.
Attendees of the shows included Anthony (Tony) Wilson, who was supposedly inspired to start the independent record label Factory Records, and Peter Hook, who co-founded Joy Division and New Order and was said to have bought a bass guitar after the concert.
Other audience members included The Smiths' frontman Morrissey, singer and songwriter Mick Hucknall of Simply Red and The Fall’s lead singer Mark E Smith.
