Former The Clash rockers Mick Jones and Topper Headon have returned to the studio together for the first time in 27 years to help British prisoners.
The pair re-recorded the band's classic Jail Guitar Doors for a charitynamed after the track - which was set up by Billy Bragg to help prisoners put their criminal past behind them by concentrating on music.
It was really touching to think we've helped, even if it's in a small way
The cause, founded in 1997, buys musical instruments for inmates to learn behind bars.
Jones and Headon headed into the studio, along with four former prisoners and Bragg.
And the pair were glad to help - because they learned how much the charity had made a difference for the ex convicts' lives.
Jones says, "The guys were telling us how much this scheme had helped them move on from their previous lives before prison. It was really touching to think we've helped, even if it's in a small way".
Headon recalls how having access to a guitar during his own stint in prison for drugs charges put his life in focus "When I was in prison myself, many years ago, I was lucky enough to have access to a guitar, which belonged to the prison vicar! I know how much it helped me get through it".
