Fans of The Clash have been treated to a collection of "lost" music and film footage.
Surviving band members Mick Jones and Paul Simonon appeared on BBC TV's Newsnight show to promote the reissue of their landmark 1979 album London Calling.
And to the delight of Clash fanatics, last night's show aired previously unheard tracks - which will feature on the upcoming 25th anniversary reissue - and unseen film.
The unreleased demos make up part of the so-called Vanilla Tapes, a collection of long lost Clash recordings recently rediscovered by guitarist and singer Mick Jones in an old cardboard box as he prepared to move house in London.
They were taped at the band's favoured rehearsal space known as Vanilla, in Pimlico, central London, in summer 1979, only weeks before the "proper" London Calling sessions were recorded at Wessex Studios.
Jones says: "I recognised them instantly for what they were. Then I put them somewhere and I had to find them again. But I sensed where they were and that took me to the right box. I opened it up and found them. They hadn't been heard since before the record was made. It was pretty amazing."
Iconic frontman Joe Strummer died of a massive heart attack in December 2002.
The anniversary edition of London Calling is released on 21 September.
