Memorabilia signed by the Sex Pistols during a visit to Keighley 25 years ago is to be auctioned at Sotheby's.

The autographs - on a torn sheet from a notebook - were obtained when the controversial band played at the former Nikkers night club in December 1977.

A gummed "God Save the Queen" sticker and letters of provenance, which also form part of the lot, were obtained with the signatures by the then DJ at the Cavendish Street club.

The items together are expected to fetch between £500 and £700 when they go under the hammer at Sotheby's in Olympia, London, on Tuesday.

The lot is among 200 being auctioned as part of a special stage and screen sale, including a huge range of film and rock memorabilia.

Other lots will include a host of Beatles items, among them the first known published photograph of John Lennon and Paul McCartney on stage.

The Sex Pistols' Keighley performance had been in jeopardy because vocalist Johnny Rotten was suffering from a sore throat - the band had cancelled a concert in Wolverhampton the night before - but the gig went ahead.

The band performed for about an hour and a quarter to a 500-strong audience.

Members of the press were banned from the venue by tour organisers because of "adverse publicity".

The Keighley concert - part of an eight-stop nationwide tour - was arranged by Nikkers owner Ian Barton as a thank you to regulars at the club's weekly rock nights.
